We've had this for years and love the convenience of never carrying a key. The unit has stopped working without reason twice and customer service was accommodating and quickly replaced it with an updated one. Now, whenever the weather changed drastically, the bolt either doesn't open or close all the way so it makes entry/exit a bit more difficult. My wife often finds herself stuck outside with baby and bags in-hand until she can reset the bolt and enter the code again, hoping that it opens all the way to clear the striker plate. I called and customer service walked me through troubleshooting by resetting the bolt but that has not fixed the issue. Great technology but it's evident that there is a need for minor improvements.
