Familiarity: I've used it once or twice and have initial impressions
I bought femto front and rear lights for my wife's cruiser, and the rear one didn't work. The button on the rear light would stick and made it useless. Chainlove refunded my money, but I wouldn't buy this. It's weird, since the front on works so well.
