After a recent surgery, this went from 'neat gadget' to 'incredibly helpful'. The ability to have people come and go without me getting up is great, and with the ability to create single-use codes not using your personal code it is possible to make sure temporary visitors don't reoccur once you are up & about.
Installation required a larger hole than the standard deadbolt, along with a little creative chisel work around the plate. The mechanism makes a mechanical noise, but is solidly built and I've had no complaints so far.
Shipping was quick, ATG clearly knows what they're doing.
Templates for holes and instructions were extremely easy to follow. Deadbolt is work great - love the auto lock feature - locks the door even when I forget. Having the ability to pass out a one time code, when I prefer not to hand out a key is also a very nice feature.
