This is my fourth Luci light. They come in really handy, but the snaps don't stay snapped and the USB port takes a little jiggling to keep it charging. I fixed the problem by using a little drop of super glue gel, but I shouldn't have to do this. And I like the option to plug it in to charge, but I have to wiggle it around a little bit to get the lights to turn on signifying it's charging. This will probably be the last time I order this product. I'm hoping they come out with something a little more sturdier and reliable.
