Be careful when removing the plastic battery protectors from the battery packs when you replace them. I broke one off when I first replaced the battery. With my old eyesight I missed that one of the disks broke off the tab. I have one that resides in my watch pocket and is used at least 2 or 3 times each day. Although I have lots of other flashlights, this one is always with me. I bought 30 Pico's over a year ago and gave lots of them to friends and family. Out of the bunch one of them had the battery protectors in it.

Great tool and great company!

The best,
