The engineers who designed this don't have one of these at their house!

Reason is- the back lighting does not turn on when you enter the code!  So- imagine this- you are trying to enter the code- but you cannot even read the numbers!

What is super dumb about this is- the lock has a light - but the numbers only illuminate when after you lock it (turns green) to tell you it is locked.

But- the numbers do not illuminate when you are entering the code- which is very difficult to do at night!
