Once it links up to boiler WiFi adapter, it works well. Can be a little slow to connect to adapter, sometimes seems to not be able to connect. My phone slows down quite a bit after I use this app, other apps had a hard time connecting to data, and my battery depletes very quickly. After I uninstalled it, phone went back to normal.

So far, so trashy. iOS app and Android app both search indefinitely for the controller. My android phone sees the Bluetooth device, but the app never stops searching. Cheaper manufacturers have this stuff down pat.

Can't even create a login. Went on website and created login just to have US Boiler deny my request. Can't even use what I paid for. Stay away from this!!!
