Meh.
First of all, the lantern itself is great, amazing battery life and very good illumination. If you want to check the battery life you need to press the power button which then switches off the light, a bit annoying yes. So get the app they say, well here is the problem with the app: 1. Once you have the app set up to recognize your light, you need to close and restart every time with your phone no more than an inch away for the app the find the light. 2. The battery indicator doesn’t give any indication of how full your battery is, a percentage would make sense don’t you think?
