[Thumper]

I have been using the PT rage lights for a couple of seasons now and have had great luck with the lights. Twisting the light on can be a pain, I find if you use a little grease like super lube on the plasitc threads and o-ring it makes it much easier to turn and wont lock up on you. Great little light you can wear around you neck or tuck in your bag and not even notice.
