Review: Works as well as shown. No nonsense product. Easy to install. The directions are idiot proof. Check the existing holes if replacing a knob.
Review: Being used on interior door in temperature controlled environment. Cannot comment on extremes of temperature. Instructions for install and all other functions were easy to follow. NOTE: I have intermediate skills in construction, computers and electronics. My purchased security knob was put on a door that had already had the holes cut for a door knob and was replacing an existing knob. Had to do a bit of chiseling to fit latch plate as it was bigger than my old plate, but, my old latch plate would have worked. Got the silver colored knob. Old one was brass. So didn’t really match the old latch plate. Was easy to chip out with a sharp chisel and steady hand. Did a dry fit first and trace around new latch plate where the jam needed to be cut. Easy Peazy. My favorite feature is how it keeps prying eyes from learning your code by allowing you to punch in up to 41 other numbers to disguise your code. It works as long as you punch your code in the proper order somewhere in that series. Which makes using a shorter passcode less risky. You get to program your own passcodes and they can be basically any length up to a ridiculously long one. Make sure you change the master immediately though. Can also have different codes for different people. There is an app for tracking but I generally do not use apps for things like this for personal security reasons. So cannot speak to app functionality. Knob has the ability to use a key and that has a separate mechanical mechanism. Comes with two standard style keys. Both worked and mechanism was well made. Have not yet tried the USB C function to unlock when batteries die. Opens fine from inside of room because interior knob is not tied to the electronic locking function. Feels very heavy duty. Will be used infrequently. But will update this review if needed in the future. Am considering getting another for exterior door. Am very pleased with this security knob. It is well thought out and the functions I have tried have all worked well.
