    5 of 5 Great OEM Switch January 18th, 2023
    by Edgar from Alexandria, VA

    The existing switch for our under cabinet lighting was acting up and sometimes not shutting off. Found the exact replacement here and it was quickly shipped. Fit perfectly and everything is working properly!

  • 5 of 5 Great little dimmer June 14th, 2023
    by Ronald from Freeland, WA

    Matchbook-sized dimmer that taps on and off, dims smoothly, and remembers the last setting. Comes with 2-sided tape to attach easily.

    Good service. Had parts i needed in couple of days.

  • 5 of 5 | June 19th, 2026

    Tried finding the hinges elsewhere. Found them right away. Perfect match.

  • 4 of 5 | June 18th, 2026

    I was able to find the exact hinge needed to replace broken hidden Soss hinges in a Martha Washington cabinet. The price was reasonable. It did take a while to ship out (ordered May 15, shipping notice June 2) but then arrived quickly once shipped.

  • 5 of 5 | June 18th, 2026

    I have looked and looked for replacement parts for my cabinets and was about to give up hope, but thankfully they had the exact parts I needed. They arrived quickly, reasonably priced and I am thrilled.
