Great little light
Used for 7 to 12 months
Lighten up people it's £2.99. I use on the back of my mountain bike on these dark nights. I lose lights for fun so for me great unit. It doesn't like water that's clear, just silicone it up. I never have issues once this is done. Cheap enough to carry a spare so no big deal anyhow. In perspective I spent £300 on my front light....
Not to be trusted
Used for 2 to 8 weeks
Had this item 4 weeks now. Using it every night on my commute home in the dark. Twice it has turned itself off mid-journey. VERY dangerous. Doesn't seem to be able to cope with wetness/coldness. Often gets stuck on one mode - only way to turn it off is to remove batteries. Would advise you spend a little more on a different product.

Decent rear light for Cycle
Used for 2 to 8 weeks
The light is user friendly. Easy to start and easy to set up. Once installed remains fixed at the place, does not move or get lose. Uses coin cell/battery, which go reasonably long. Coin cells can easily be replaced once over. Visibility Range is decent. Has two option of operating the light one in on mode and one in blink mode.
