Like many here, i carry a ResQme, just in case i need it. I really like it because of it's small size and portability. A life-hammer is a good alternative, but since i don't own a car and always drive a company or rental car that just not practical.

Mine has been hanging on mine flashlight holster for awhile (handy D ring on the holster). Some two weeks ago i noticed, the inside of the ResQme to be rattling. So i tested the ResQme and it failed to deploy the center-punch.

I mailed ResQme after i noticed the problem and even offered to send mine broken one for inspection, but they didn't respond. So guys if you hear yours rattle, toss it and get a new one. Or get a lifehammer which doesn't have anything that can fail.
