The app itself is easy to use. The problem is it doesn't work 90% of the time. the lights are supposedly connected but unresponsive, then they disconnect & refuse to connect again & support is minimal. "let me tell you the same 3 steps repeatedly & refuse to acknowledge that they're not working" They call it a chat but it's not like you're connected with someone who answers in a reasonable timeframe, you will wait for hours. The app doesn't even give notifications when they do answer. -10/10
