Yes and No!

I have 3 of them, well okay actually 2, because my girlfriend has one of them. I don't seem to have many problems with them, other than over time the O-rings have become stiff from age. I have actually replaced 2 O-rings on one flashlight alone. I keep these around simply because they are small, somewhat lightweight and easily packed. I also have a Mag Solitaire and it has become part of my EDC kit. The nice thing is, I found 2 of them and the third was a gift with the Solitaire. No, I do not carry the Mini-Mags everyday.
