Don’t buy it. We have The Sting and it is a great concept and the build is pretty good. However we are so extremely disappointed and frustrated because it just does not work. Never connects or stays connected, rights change every time, the app is very limiting. I do hope they continue to fix the connectivity issues. This thing would be worth 4x as much in the lifestyle if it worked effectively.

Worst app imaginable never works device keeps disconnecting or not working at all. I have it set to English yet still 75 percent Chinese. Most of the English makes no sense. Just as awful as it can get

Unit will not stay Bluetooth connected unit will not unlock if under any stress needs the controller their to lock the unit does not just snap closed Good idea if worked needs improvement

I have tried to make an account and the app never lets you select an country/region so you can complete the process
