Door knob

Not bad for the price. Does it job. Lock works great. Easy to install. Very strong material. The look is ok for the price .

As advertised!

The media could not be loaded. Very pleased! I picked this one because I saw it has a tiny the little white piece and thought it was just what we needed because the hole is all messed up and making it a loose fit. So I used it and it made it a perfect fit! Installation was easy and fast. The key functionality is smooth. Price is very affordable. Color matched my dead bolt lock! Lock functionality is perfect 🤩 it is very study and it came with three keys! I was shocked to see how nice it is for the price. I feel like it won’t be as easy to break in with this lock! I definitely recommend this set up for anyone looking for a knob that locks!

Amazing quality

I have bought many locks and none as easy and fast to install, I loved it and maybe 5 minutes to install.I highly recommend this one.

Decent Doorknob

Works for me. It came with instructions to install and 3 keys. I have been using it for about four months with no issues, and I expect none in the future.Ease of installation:Incredibly easy to install with step by step instructions. Just make sure not to close the door while you're installing it, or you will be trapped.Durability:Durable, no problems after 4 months of use.Weight:Lightweight.Functionality:Incredibly functional, difficult to lockpick.Quality:Good quality for the price.It's only 4 stars as the keys are the exact same for every doorknob you buy! If you buy two for two doors in your house, they'll use the same key. If you're looking for that, hey, maybe its a positive. If not, consider buying a similar product for different keys.

Locks keep reengaging and can't be unlocked from inside.

So, I know I was going for cheap and got burned, but wow. It was kind of wobbly loose from the beginning after installing it and just continued to get worse.One day I went to leave an it was locked, but no amount of turningthe knob or locking bit back and forth ( or round and round and round in this case) would release it. I ended up going around the house from the other door to open it with a key. It was fine a few days and then did it again. Now a week ish later it just relocks any time I turn the knob after unlocking it. I haven't even had it a full month and didnt get it installed immediately when it did arrive.

Decent but be careful

The doorknob functions great, the key works properly with no issues. The assembly was nice and easy and all the necessary items were included. My issue is the knob itself and how it feels when you open and close the door. I don’t know why but the handle is almost razor sharp. It has cut me a few times already and nearly did a couple of other times. Had to use a grinding pad to buff it down some.

Tough Lock. Nephew locked the door I had to kick the door in to get it open.

My young nephew locked the door and I got out the creditcard and flathead screwdriver. Nothing would open this door. I then got my reciprocating saw and began to saw at the lock to no luck. I had to kick the door in to get it open finally jamming the lock in the process. 10/10 tough lock.
