Matt, no doubt a quality light but rather pricey at $46 (incl. S&H). I have a couple of Garrity key ring LED's which I got at WalMart. They are well made coin cell lights measuring 2 3/8 long by 1 wide by 1/4 thick. (Imagine the thickness of two sticks of chewing gum but shorter). Momentary on switch is a little stiff on some. You can test it thru the packaging before you select one. Cost with tax: less than four dollars. It is blindingly (?) bright and never seems to diminish. The battery is replaceable if you have a small enough Phillips to remove the six screws holding it together. I'm talking TINY! <img src="/images/graemlins/smile.gif" alt="" />
