I am using Samsung digital lock model SHP-DP609. It is the latest model in the market. Is it good? The design is premium and it is very simple to use. It also has many good security features. But it is not reliable! Installed barely 7 months and the front panel got issue. The service guy told me apparently it is a very common problem! So if it happens out of the warranty period, it can cost you easily $200 to get it replaced! So I think the moral of story is always not to get the latest model. Get one generation backward. It is more stable.
Is It Good??
