  1. bookfriend

    We loved these for the price when shopping for them but now that we got them and have them installed we love the classy look it gives our white doors and they work very well for us. Would recommend

  2. N.Franco

    Switching every door knob to this brand!

  3. susan werner

    Liked everything about the knobs

  4. Jason Gresock

    Easy to install and great product for the cost

  5. SueSue

    We wanted to update our doors from the standard brass looking cheap ones and these knobs were the ticket! Mu hubby easily installed them all and they are working nicely. The sets come complete with striker plates, so this 6 pack is an affordable way to update your decor. Now we just need to update the hinges.

    I ordered these to change out all the doors in my house so they could finally match. The black stands out and the price even more so. I probably would have paid double the amount for black knobs at the stores near me and they wouldn’t have been locking ones. Another good thing is if a door is locked and you need in all you need is a coin.

  7. Hugh M.

    Overall good item, knobs seems stride inners seemed a little cheesy but over all not bad. As other said I had to modify the opening to accept the striker plate and latch

  8. Mr. CarterMr. Carter

    Paint and hardware is extremely durable.

  9. Sundown Enterprises

    Exactly what I needed, easy to install, and are standing up to my five children.

  10. Cristiano

    Easy to install and made my doors look a lot better than the old gold knobs
