Light

Love the size. Love the ease of charging. It needs an on/off switch. Turns on constantly. Just putting it in my pocket or picking it up turns it on

Could Be Better

The amount of light and ease of charging is great. However, the inability to lock the light so it does not inadvertently turn on while keys are in pocket is a huge drawback.

Hoped For Better

Love the light, but it turns on in pocket to easily. I have to recharge way too often and I couldn't recommend for anyone that wants to carry it on their keychain.

Hi James! Hold the power button down for 5 seconds until the light blinks twice. Then it will be in transportation mode. This is highlighted in the manual.
