It’s a door knob
Was easy to install using precut holes on the door and fit with no additional work. Works as it should and the lock keeps out prying eyes.

Nice and easy
I'm stuck with returning it sadly. Doesn't fit into the previous door holes and set up before trying this. Sucks truely does I was hoping to have a locked door for my daughter's room bc she's like that so nobody can go in it while her and I aren't home. Since we are in an apartment there's nothing we can do about it. 😞😔

pretty low quality lock.. but worth the price I guess
I bought this because I needed a bedroom lock, and it was not too expensive. The lock installed easily but the action and smoothness of the lock is absent. Sometimes it takes a few tries to lock it also.. not sure why. If I had to do it again, I would spend a little more money for a slightly higher quality lock mainly based on the rough action.

Perfect Doorknob – Stylish, Sturdy, and Smooth!
The quality is outstanding—it’s made of durable materials, feels solid in hand, and operates smoothly without any sticking or resistance. Installation was a breeze, thanks to the clear instructions and included hardware.

Smooth operator!
Won't take longer than five minutes to install (if it's a replacement) - and it'll probably give you years of operation.
