Works great. And looks pretty descent for price.
Door locks smoothly and not an abrasive look.Looks simple but not bad. Color and sheen fits modern look.

Had to Change the Locks
I have 3 outside doors and all different keys in this house that was a formal rental. Changed the key cylinders on the dead bolt. On two I could use the same dead bolt and thumb switch. I just had to pre rotate the key 1/2 turn to get the correct action. On one I replaced the entire deadbolt mechanism. Everything work on 1 key and I have 9 keys all the same.

Poor quality
I spent all day to get this to line up properly and to get the lock to work. Now, I can't get the key out unless I unlock the lock. What good is that!? How is that even possible? I read another review with the same problem. Next time I will spend a little more money and waste less time.

Smooth operation
Not bad to install. A little tricky at first. Once done, it’s a nice modern looking product that is easy to use. Functions very smoothly.

Dead Bolt
Easy to install and replace the old one that was broken. Local stores couldn't match the old one with anything they stock. Smaller type dead bolt needed and this one fit perfectly! Popped it in in only ten minutes!

Easy Installation
The product is quality. The directions were a breeze for this 60 year old woman to follow. I believe that for the price, you get a lot! I always enjoy when that happens!
