The Real Deal - Mark 3 - 2.1 oz for the 2x3
This is the real deal - from what I read (not from experience) this does seem military grade. It has a reflective grid in the center hole that helps you pinpoint where you are aiming, and the instructions on the back are really helpful. I believe this reflective grid is what makes this mirror Mark 3.Some people complain it is heavy. Ok, sure, for the size it feels heavy. But the 2x3 size is 2.1 oz (60 gr) - in my mind, totally acceptable. It is a real mirror, but well built and rugged. I will still wrap it in something useful.I am buying two more. I totally recommend.

The Real Deal
This signaling mirror is the real deal. Well made and works well in the field. It's no wonder the military issues them to the troops. A little pricy but you get what you pay for and and this is well worth every penny.

No complaints at all!
I accidentally ordered the 3 X 5 inch mirror initially. It was too big for my liking so I arranged for a return. I ordered this, the 2 X 3 inch beauty. The quality is remarkable and, if I didn’t know better, I’d say it was made from bulletproof glass. What a beautiful product. Oh, and about the return, my 22 year-old son forbid me to return it. He loves it and it resides comfortably in his pack now. Thanks for a surprisingly great product!

Product is durable, handy and when needed does the job.
Product came intact and ready to use, instructions clear to follow and when needed will be essential and quick to employ for signaling purposes.

quality high
Have with other essential emergency/survival stuff. Size is right for that,however if bulk isn't an issue would use the larger full size mirror.takes a sunny day to acquire understand the aiming method, bit dim in cloud.requires a bit of traing. See old military film on youtube
