UST StarFlash vs Coghlan's 9902

Buy the Coghlan's signal mirror, model 9902, UPC 056389099029, ASIN B000C8BEEG, when you want the glass mirror whose size cell says 2 by 3 inches and whose description says 1/4-inch laminated glass with a sight grid, and when you will ignore a dimensions cell that says 2 inches by 2 inches. Buy the UST StarFlash, ASIN B075S4XZKB, when you want the signal mirror whose product description names a floating polycarbonate mirror and a smaller micro mirror on the same page, and when you will accept that this listing did not show a model number, a UPC, or a size selector. These are signal mirrors. They are not flashlights and they are not whistles. They throw sunlight. They do not throw a beam of their own.

Short version. A survival kit is the pouch these mirrors are supposed to live in. A Fox 40 and a Storm whistle make noise when the sun is gone. A Midland weather radio and a RunningSnail crank radio are the powered way to hear a forecast. A mirror is the silent tool. Match the model before you match the word signal.

The Coghlan's title is a survival signal mirror, size 2 by 3 inches, highly reflective laminated glass, compact, lightweight. The brand cell says Coghlan's. The model number and the part number both read 9902. The UPC is 056389099029. The GTIN is 00056389099029, the same digits with a leading zero. The ASIN is B000C8BEEG. The manufacturer cell says Coghlan's. The size cell says 2 x 3-Inch. The item-type name says Signal Mirror - 2" x 3". The included-components cell says Signal Mirror - 2" x 3". The recommended-uses cell says Outdoor, Survival, Emergency. The number-of-pieces cell says 1. The number-of-packs cell says 1. The unit-count cell says 1. The color cell says Signal Mirror. Signal Mirror is not a color. It is the product, filed in the color slot the way other cards file a series name in a color slot. The material cell says Blend. The description says 1/4-inch (6.3 mm) laminated glass and a sight-grid retro-reflective mesh. Blend is the vague cell. Laminated glass is the description. A sight grid is how you aim the flash. The card does not print a candlepower, a range in a cell, or a mile rating in a cell.

The item-weight cell says 0.02 kg. Two hundredths of a kilogram is 20 grams. The card does not print an ounce weight beside it. A 2-by-3-inch piece of laminated glass can land near 20 grams. A plastic mirror often lands lighter. Weigh it if the mailer weight is what you are comparing. Do not convert 0.02 kg into a second official cell. The dimensions cell says 2 inches long by 2 inches wide. The size cell, the title, the item-type name, and the included line all say 2 by 3. A square 2-by-2 cell and a 2-by-3 size cell cannot both be the glass. Measure the rectangle. If it is about 2 by 3, the dimensions cell dropped an inch. If it is about 2 by 2, the size cell borrowed a 3 from a different mirror. The description repeats 2 by 3. Four fields against one field. The dimensions cell is the outlier. Do not average 2 and 3 into a 2.5-inch square and then cut a pouch for the average.

The UST title on ASIN B075S4XZKB is UST StarFlash Signal Mirror. The product description says the StarFlash has a built-in aiming system, is available in two models, a larger floating mirror that will not sink and a micro-sized mirror, is handy for grooming, has a lanyard hole, and works in overcast light or by moonlight. It then prints two sizes in the same paragraph. The standard size measures 3 by 2 by 0.25 inches, height by width by depth, and weighs 0.7 ounces. The micro measures 2 by 1.5 by 0.1 inches and weighs 0.5 ounces. It says the micro is not a floating mirror. Both are backed by a limited lifetime warranty in that paragraph. The page did not show a model-number cell, a UPC, a GTIN, a size chip, or an included-components cell when it was opened. It was unavailable. Unavailable is stock. The missing selector is the ordering hazard. One ASIN describing two mirrors, without a size cell that picks one, means you do not know which rectangle the warehouse will pick if a warehouse picks at all.

The description's standard size is 3 by 2 by 0.25 inches. The Coghlan's size cell is 2 by 3 inches. Those are the same two edge lengths written in opposite order, plus a thickness the Coghlan's dimensions cell never printed and the Coghlan's description did print as 1/4 inch, which is 0.25 inch. Thickness can match while the material does not. The UST paragraph says the mirror is virtually unbreakable and, for the larger one, floating. The Coghlan's description says laminated glass. Glass and polycarbonate are not the same sentence. The UST page's own description does not print the word polycarbonate in the text this opening showed. "Virtually unbreakable" and "floating" are the claims. Do not add a resin name the paragraph did not use. The Coghlan's card does not say the glass floats. A glass mirror in a river is a sunk mirror. That is the practical split, and it lives in the UST description's floating sentence and in the Coghlan's silence, not in a shared float cell.

Weights do not match, and they should not, because they may not be the same object. Coghlan's cell says 0.02 kg, about 20 grams, about 0.7 ounces if you convert it. The UST description says the standard mirror weighs 0.7 ounces and the micro weighs 0.5 ounces. A converted Coghlan's cell and the UST standard weight can land on the same 0.7 ounces. That is a conversion, not a cell that says the two products are identical. The UST micro at 0.5 ounces is lighter and, by the same paragraph, does not float. If the unmarked StarFlash shipment is the micro, you did not receive the floating mirror the first sentence advertised. If it is the standard, you did not receive the micro. The page gives you no model cell to check against the bag. Coghlan's gives you 9902.

Who should buy the Coghlan's, and who should buy the StarFlash?

Buy 9902 if you want UPC 056389099029, the 2-by-3 size cell, the laminated-glass sentence, the sight-grid sentence, and a single piece count, and if you will ignore a color cell that says Signal Mirror, a material cell that says Blend, and a dimensions cell that says 2 by 2. Buy the StarFlash ASIN only if you want the aiming-mirror description and you will measure which of the two sizes arrived, because the page did not choose for you. Buy the Coghlan's if a reorder has to be a barcode. Buy the StarFlash if "virtually unbreakable" and a possible float matter more than a model cell, and if you will send it back when the micro arrives and you wanted the floater, or the other way around.

Do not buy either mirror as a flashlight. The Fenix PD35R+ORG and the Streamlight 88082 are the lights that make their own beam. Do not buy either as a whistle. The Fox 40 card is the noise. Do not buy a second Coghlan's to fix the dimensions cell. One order is one mirror. Do not buy the StarFlash as a two-pack. The description says two models exist. It does not say both are in the bag.

What is 9902 actually for?

Aiming a patch of sunlight at a rescuer, or checking a tick bite and an eye, with a glass rectangle the size cell calls 2 by 3. The useful identity is 9902, the UPC, the GTIN, one piece, the glass thickness in the description, and the sight grid. The color cell is noise. Blend is noise until you are holding glass. 0.02 kg is the weight cell. 2 by 2 is the dimensions cell you test and then set aside if the glass is 2 by 3. The recommended uses are outdoor, survival, and emergency. Grooming is not in the Coghlan's use cell. The UST paragraph is the one that mentions grooming. Do not expect a magnified shaving mirror. A sight grid is a hole and a mesh, not a 10x lens.

The grid works when you can see a bright spot on the target through the hole. The card does not print a practice distance. A mirror flash is a line-of-sight tool. Trees block it. Night blocks it except for the moonlight the UST paragraph mentions, and the Coghlan's card does not make that moonlight claim. Pack it where your fingers can find it without unpacking the stove. The survival-kit article is the pouch conversation. This card does not include a lanyard in the included line. The UST paragraph mentions a lanyard hole. The Coghlan's description, in the lines this page printed, does not. Do not expect a cord in the 9902 bag unless it is there when you open it.

What is the StarFlash listing actually for?

A signal mirror with an aiming star, sold under an ASIN whose description covers two sizes and whose opened page did not show a model cell. The useful identity is the ASIN B075S4XZKB, the brand UST in the title, the aiming-system sentence, the lanyard-hole sentence, and the two size-and-weight pairs in the same paragraph. The floating claim attaches to the larger mirror. The micro is excluded from that claim in the same paragraph. Lifetime warranty language is in the paragraph, not in a warranty cell, because the warranty cell was not on the page. Grooming is a secondary sentence. Overcast and moonlight are in the paragraph. They are not a lumen rating. The mirror does not make light. It redirects light that is already there.

If you order this ASIN, put a ruler on the mirror the day it arrives. Three by two by a quarter inch, at about 0.7 ounces, is the standard pair. Two by 1.5 by a tenth inch, at about 0.5 ounces, is the micro pair. Anything else is neither sentence. A float test in a bowl tells you which claim you received, and it tells you faster than a model number this page did not print. Do not drill a second hole if the lanyard hole is already there. Do not expect the Coghlan's UPC on the bag. This listing did not print a UPC to match.

How do you aim one without mixing the two cards?

Hold the mirror close to your eye, catch the bright spot the grid or the star throws, and walk that spot onto the target. The Coghlan's description calls the mesh a sight grid. The UST description calls it a precision aiming system. They are the same job in two vocabularies until you are holding both and the holes differ. Practice on a tree before you need a ridge. Do not flash an aircraft you are not trying to signal, and do not flash a driver on a road. The cards do not print that courtesy. It is still the way the tool works. A mirror is useless in a closed canopy at noon if you cannot see the sun, and it is useless after the sun is down except for the moonlight sentence on the UST page only.

Glass breaks. The Coghlan's card calls the glass laminated, which is a shatter claim, not a claim that it cannot crack. The UST paragraph says virtually unbreakable and does not print a drop height. Pack the glass flat, not on a stove. Pack the plastic one where it will not be scratched into a dull plate. Neither card prints a scratch rating. A dull mirror is a grooming mirror that failed the signal job. Wipe it. The whistle is the backup when the sun is gone. The radio is the backup when you need a voice. The mirror is the thing that works when the batteries in those other tools are the problem.

What actually fails on these two cards?

The Coghlan's card fails when 2 by 2 is cut into a pouch and the 2-by-3 glass will not enter. It fails when Signal Mirror is read as a colorway you can reorder in red. It fails when Blend is read as a plastic mirror and the glass sentence is ignored. It fails when 0.02 kg is treated as 0.02 ounces. It fails when a mile range from a different mirror ad is pasted onto 9902. This card does not print a range. It fails when a lanyard is expected because the other brand's paragraph mentioned a hole.

The StarFlash card fails when the buyer thinks one ASIN is a chooser and receives the micro instead of the floater, or the floater instead of the micro. It fails when both sizes are expected in one bag. It fails when 0.7 ounces and 0.5 ounces are averaged into a mirror the paragraph never described. It fails when "virtually unbreakable" is read as a license to pry with the mirror. It fails when a missing model number is filled in from the Coghlan's 9902. It fails when unavailable is read as a spec. It is stock.

What is this comparison not?

This is not a measured flash distance. Neither card prints a test at a named mile. This is not every UST mirror. B075S4XZKB is the StarFlash page that describes two sizes and prints no model cell. A different UST mirror with its own model is a different ASIN. This is not every Coghlan's glass. 9902 is the 2-by-3 card. This is not a price quote. Use the buttons. This is not a whistle test, a radio test, or a flashlight test.

So which signal mirror should you buy?

Buy the Coghlan's if you want model 9902, UPC 056389099029, the 2-by-3 size cell, and the laminated-glass sentence, and if you will throw out the 2-by-2 dimensions cell, the Blend cell, and the Signal Mirror color cell. Buy the StarFlash if you want ASIN B075S4XZKB and you will measure the mirror against the two size pairs in the description, including the float sentence that applies only to the larger one. Buy neither if you wanted a flashlight, a two-pack, or a range number these cards do not print. The model stamp is the decision on the Coghlan's. The ruler is the decision on the StarFlash, because the stamp is missing.

A shop clip that shows both 9902 and this StarFlash ASIN, side by side, is not on this page. Use the cells and a ruler. Do not treat a grooming-mirror video as a measurement of the 2-by-2 cell.
