2 stars because it's everything you expect except:

1) you accidentally brush it and it locks/unlocks. Someone recommended a two touch feature, I second that notion... This happens all the time, very annoying.

2) It does not integrate with homekit/siri... Even after spending another $90 for kevo plus wifi... Missed opportunity in a big way.

3) Made me pay another $90 for kevo plus, after I already spent $200 on an over priced, under featured door lock just to get a feature that you should have put in the lock already. AND DIDN'T EVEN HAVE KEVO PLUS WORK WITH HOMEKIT/SIRI?!?!

I would restore 1 star each for:

1) a double touch feature (or any feature that didn't make the accidental lock happen ALL THE TIME)

2) Integrate with homekit/siri

3) Refund my $90 for Kevo plus
