Review on Bike Spoke Reflectors, 12-Pack by Kikkerland - BB34 by Joe Gilmartin

I bought two pairs of these indicators and one of each pair had dead batteries on arrival. The batteries are two 3V CR 1220 lithium cells which are not only expensive and difficult to replace but are held together with a small piece of copper VERY weakly soldered to the circuit - one of those clips just fell off one of the blocks as soon as it happened I opened it I don't actually have a soldering iron and am considering borrowing one from a friend to try and fix this seemingly disposable piece of crap. However, the ones with working batteries will work. ok, and if you run into the same issue, Revain's refund policy might cover DoA refunds.
