Bests & Worsts Reviews from Amazon

When I ordered these pathlights (along with a spotlight and bridge) the original release date was pushed back one month. I feel like it should have been further delayed as these don't seem to be ready. When they did arrive the first pathlight installed using the bridge/app without issue. The second one would not install. I've tried reinstalling the app, removing the bridge and adding it again, different batteries...everything I could think of. This second pathlight just will not install so it's in use but I can't control it like I can the other one.
