I was looking to replace shiny silver rectangular knobs that never looked straight with something round and black. These knobs were the perfect replacement and the least expensive option I saw anywhere. They're metal and sturdy, though they've only been installed for about a week.
Needed this larger size knob for two cabinet doors, to match the ones I already had in the kitchen but were no longer carried by home depo or Lowes. Ordering was easy and shipping was reasonably fast. I would recommend MYknobs to anyone looking for a hard to find items.
These were exactly what I wanted and look great on my cabinets. The only snag I hit was for the knobs they only give you short screws and I needed long ones as some were going on drawers. Fortunately the screws that came from the drawer pulls that I took off fit the knobs and that fixed that problem.
