TTLock

Constant unnecessary app changes and an app that takes up 2GB of phone space. Improve security, reliability of Bluetooth connection to gateways, don't change the app background to just say there's an update. The app doesn't even look the same as shown in the Google description.

Thumbs Down Lock doesn't always function properly have to change batteries frequently. Sometimes the lock doesn't work at all even with new batteries. Features in the app doesn't make sense. There isn't a true battery reading.

works ok, I reset the lock now some of the features don't work.and there is no customer support at all. so buyers be ware...and says it work with Google home and Alexa but it didn't work for me. all all my other smart devices work with both of them. including my smart Bulbs
