I ordered this keypad door knob and it works great at my business! It makes it easy for each tenant to access their rooms and for admin to get in with no problem! Super easy to install also! I’ve ordered a total of 9 so far and will be ordering more!

This was super easy to set up. Honestly, I actually put off installing it because I was worried about how difficult it might be. Once I set it up, I was mad at myself for waiting because of how easy it actually was. My daughter thought the fingerprint Aspect of the door handle was so cool. The directions are super simple to follow.

We got this door locked and it really works well. It does have a problem reading your fingerprints if your hands are wet or it’s very sunny. It was also a little annoying on Fourth of July when we had so many people wanting to come in and out because it was hard to get the door to stay unlocked.

It seems to work well, hopefully it lasts a long time, the passwords it generates can be made temporary, single-use and permanent. I'm just worried it won't work by being on the outside.

I already installed a Model X lock in January (I left a review) and have been so pleased with it that I thought I would try the Model S as it was discounted. I found the installation a little easier with the Model S because there was no step to set the direction of the handle. Both installations were as easy as installing any typical door handle.
Since owning a Sifely I have come to really like the lock. Programming the locks is very simple using the app. I am also using a single gateway to get both my locks on line for remote access. The gateway has to be in bluetooth range of the locks, or you may need another gateway for the second lock. I use passage mode to keep the doors unlock while I am home during the day until a set time at night and the doors lock automatically when we go to bed. I like how the phone app also works with my watch. I get a message whenever the doors are unlocked and it tells me which key opened the lock. When I leave the house I can lock the door using my phone. It is possible with the gateway to unlock the door using my phone remotely or with my watch. Because my locks are online there is also a web portal offered free by Sifely on their web site that I think is pretty cool. You can manage all your locks from this one location. I can see this being very useful for business having multiple locks with multiple locations. I was able to transfer all my codes and keys (not fingerprints) from the Model S lock to the Model X on the app in one step.
The biggest drawback I can find is that it uses 4 AA batteries. The app tells you how much energy is left in the batteries so I am not concerned it will die on me unexpectedly. They are supposed to last at least a year. I guess I will find out. I recommend the locks. So far it has been very reliable.

Two comments after reading others reviews:
1. I was offered a rebate after my first purchase for an honest review, good or bad. I was not solicited for a 5 star review.
2. To activate the touch screen, don't tap on the display, just put your finger on it and hold it there and it will turn on reliably.
