I like the lock very much and the quality is very good. I do not like how the app is made. While the app is connected you can open the lock, so it means if you are in the gym, you definitely need to put it in the locker mode, and if you forget everybody can open it with a click. I would prefer to approve every unlock from the phone, for security reasons or from the phone to be able to make only one time unlock, not to be constantly active and the only thing needed to unlock to be pressing the button on the lock itself. I would like also to be able to choose more than 7 clicks security code on the locker itself.
