I weighed them on my scale as 35 grams each with battery. I’ve been using them for about 6 months I guess. If you select postal delivery, you can have a pair for about 10 $
I haven’t had to replace the bat yet. The real charm is it’s do nothing glitter, and night safety.
As advertised, the LED lights stay off until dusk, and stop blinking a few seconds after the wheel stops moving. Pretty easy to install, it sorta clamps between a pair of spokes.
Very nice, in the sence that it is a zero hassle (at least until the bat is shot) Useful safety light. Mine have worked perfectly, the LEDS shine bright out each side, only at dusk, and flash briefly if I move the uni indoors. Sorta fun.
I waited to review them until I had an idea how long the bat would last, and if they would crap out fast.
I think this is a cool product, if you want a bright LED blinky in your wheel. The bat lasts a long time, ( I’m still on the first one)it’s pretty bright, and very much install and forget. That’s it’s best feature, how it turns itself on only with darkness and rotation. And it works for 6 months+ (hopefully more) for 10 $
