Rated 3.1 out of 5 by 7 reviewers.
Rated 1.0 out of 5.0 by Not usable! I special ordered these dummy knobs because black was not a stock finish. They were for a rental property and we were under a deadline for our first renter checking in. We installed all of the knobs hours before our guests arrived and discovered that all of the knobs were missing a retaining clip or ring. All of the knobs pulled off and we were forced to glue them in place with quick setting glue. I do not look forward to replacing them and hope we do not damage the doors in the process. Because we discovered the defect at the last minute we were forced into a difficult decision. December 31, 2013
Rated 5.0 out of 5.0 by It looks good. Make sure to read all the instructions before installing. It looks good and matches the other knobs I bought perfectly January 11, 2013
Rated 1.0 out of 5.0 by Stem will not latch into base. We ordered 4 of these because they had hidden screws and matched our other knobs. The stem of the knob would not latch into place. Contacted manufacturer and they basically said to push harder. Not possible! We returned them. March 25, 2015
Rated 3.0 out of 5.0 by works fine Ok product. Installed easily. Used for about four weeks now. Holding up fine. I am using this knob on BOTH sides of a door. The screws provided were way to long. When using on both sides, the screws need to be short enough so that they do not interfere with each other. I had to dig through my screw coffee can to find some that fit. Be careful of color if you are trying to match existing knobs. Web images aren't always accurate. This one was more polished than I had hoped. But that isn't the manufacturer's fault. July 1, 2014
Rated 4.0 out of 5.0 by Nice looking handles Nice looking handles and easy to install. My only complaint is the chrome piece that covers the screws doesn't sit flush against the door. There is a tiny gap on one side that probably only I can see since I installed it. November 19, 2013
Rated 5.0 out of 5.0 by Beautiful and great feel! These are a great knob. They feel very sturdy when you grip them and they look professional and clean. We have white molding and doors and the darker knob color is a nice contrast. My teenage son had no problem installing all 41 knobs. Delivery was timely and the knobs arrived in perfect condition with no blemishes or markings. July 31, 2012
Rated 3.0 out of 5.0 by Worth the sale price Would have much preferred being able to screw on through the handle plate. Required disassembly to install. July 31, 2012
