Review: Great product! - This is so easy to install and makes life so much easier. I wish I’d got this sooner. It took me less than 10 minutes to install and the app works perfect. There’s also a back up mechanical unlock feature which works perfect. I wish it was a bit cheaper as I’d fit one to our garage door too. Hopefully they’ll come down in price. The quality is fantastic and feels well made. One slight issue seems to be when my partner and I return home together, the lock won’t automatically open but does when we arrive home separately.
Review: Very good product. - The best product I have ever bought. Reliable and fantastic customer service.
