I bought this item to replace a Schlage keypad deadbolt that did not work as expected - I could not change the codes and it would not connect to Bluetooth as advertised. Immediately this Blackview product stood out:Unboxing: The packaging was excellent - every piece was carefully wrapped to prevent damage and the box itself had molded foam cutout inserts to house each piece. Spare parts and hardware were in separate small boxes and clearly labeled. The instructions were artfully laid on top of the whole assembly.Instructions: Clear and easy to read with QR codes to YouTube videos with visual instructions.Installation: If you already have holes in your door, this is a breeze! Took no time at all.Setup: Again, easy, with QR codes to video instructions should they be necessary. I love the fingerprint entry.Only issue: This connected to Bluetooth easily but I have a new 5G router - this product only connects to 2.4G so I can't lock this remotely (an issue since my teens always forget to lock the door). But this product locks itself after several seconds so as long as they close the door on time, this is unlikely to be a problem.
