Question: What size is this mirror?
Document: Much smaller than the Air Force general issue, but fully functional. Slightly overpriced for the size and quality. Convenient as a backup signalling device, but not effective as a firestarter or shaving mirror.
I bought this for my camping/bug out bag. It's small, about the size of a credit card. I feel it's quality by how much it weighs. It's not heavy but you definitely can feel its weight. I also bought the carry bag for it which I believe should have been included. It's a bit pricy but I'm happy with the little mirror.
made very well and compact in size. You can also use it as a personal grooming mirror.I'm waiting for my Mirror pouch then it will be completed and packed away in my EDC or BOB. for emergeny useage to signal for help or get emergency responder attention to my location.I highly recommend it to everyone. It's number one thing to have by everyone.
Well made. Not a cheap knock-off. I would have liked a larger mirror like the WWII issue, but this is small and convienent to carry. Like the small and powerful flashlights, one never knows when it will be needed. I gave it a 4 rating only because I'd prefer a little larger size that would have a larger % refelection.
If you end up trapped or stranded one day, this could save your life and it's only about the size of a credit card (but thicker).At 0.25 inches thick, the mirror was a little thicker than I expected. It measures exactly 3" x 2". What you don't see in the picture is that it comes with a white lanyard attached through the hole in the corner (mine did, anyway).
This is a high quality, military style GLASS mirror. It is made to military specifications and is very durable. Most signal glass mirrors are plastic and, therefore, not very durable. This one should survive the toughest conditions. The "sighting hole" in the center of the mirror makes it very easy to shine your signal on rescue aircraft, vessels or personnel.Although it is pricey for its size (standard military signal mirrors are larger), I highly recommend it.
I admit I did not read the description at all before buying this mirror. My father had a military signal mirror he brought back from WWII and I remember its size. It was 3"x5". Although this mirror I just received appears to be of quality construction and materials, it does not meet the military MIL specification it shows in its product name. The MIL spec (MIL-M-18371E) specifies the mirror dimensions be 3"x5". This mirror is only 2"x3".
Size 2X3 the size of a bar of soap. A military grade signal mirror is a must in my EDC & BOB. I will attach a paracord to the mirror for gripping purpose. And a Pouch is my add on with this purchase. A protective carry case is a must have to avoid scratching the mirror surface. One should consider this option. Will Update my review.8/29/2012 Recieved via 2nd Day Air UPS from shipper.

This is a real glass signal mirror with a retroreflective grid in the middle.
Fantistic mirror, I use this in the field every day and it is always on my belt with the case sold seperatly.
