I operate a addiction recovery home and this thing has seen a ton of use over the last 2 years. It gets used about 30 or more times a day and it has worked without any major issues. My one issue would be the fingerprint reader was difficult to use in the beginning. In saying that Lockly has pushed updates to resolve the issue. Their customer support is beyond excellent and very knowledgeable. I would purchase more of these in the future if the situation arises that I need them, as it looks these will be lasting for years to come!
