(This review was collected as part of a promotion.) It was super easy to install, the size is perfect, the quality looks really good, it's not  heavy, but what I really don't like is the fact that they use 4 AA batteries and I would really prefer more of the heavy duty ones, it is spring in Canada at the moment but I'm a very curious about the battery life in winter or just even fall.I got the matte black one and it looks gorgeous. I got it connected to my Google home app and works wonders, I did not have any trouble adding it to the cloud and all of that. Instruction  was super clear and easy, and I am adoring it so far . Comes with a pair of keys but gives you the option to use your old ones, I'm not too sure how cause I decided to use the new ones, so I didn't  do it that way but there was an option. it's a great product, especially if you forget the key somewhere and you can just open it from your phone or using a pass code , did I mention how happy I am ?
