I got this for a number of reasons:1) I'm trying to convert into a smart house (have this and an ecobee thermostat, lights are next on the list).2) One of my roommates loses their keys constantly, so having a keyless entry was beneficial3) We've been doing work on the house including getting central a/c and having the windows replaced, so having a way for contractors to access the house is greatI got this with a keyed entry in addition to the number pad, in case of electrical failure. However, other than testing the keys, we've yet to use them, and I installed this about six months ago. So far, the batteries have not died, and there's been no other electrical failure (knock on wood). I've read a few reviews saying that the key pad wasn't responsive, but neither I nor my roommates have had any problems with that, though it did take a few days to figure out what they meant by "back of the hand to activate" was actually "back of the fingers". We got the hang of it in less than a week, so I'm not sure what else to suggest to people having problems.The nickle finish is smooth and sleek looking. It's quite pretty, and matches a lot of the brushed nickle objects I have in the house.The only hiccup I had was getting it on the wifi, but after I plugged my smartthings hub in closer to the lock, I was able to connect it with no problems, and it stayed connected even after I moved the hub back to its normal location.I especially like that I can lock or unlock from my phone, so that when I come home with a lot of groceries, I don't have to worry about fumbling for keys or stopping to put in a code. I can just unlock it from my car before I even start picking up my grocery bags.This lock was an investment because of the price, but I'd definitely say a good one.Note: I had a pretty smooth installation, so I can't say whether support is good or not for those who have problems. Hopefully, everyone else purchasing this product has as easy an install as I did.
