I bought this pack. Most worked, but at least two just didn't work and the only solution was to pull a new one out of the box. The quality control is questionable, but they do work. some of the LEDs still flicker with these switches, which is frustrating but I would have to waste another one to get it perfect and it's a waste.

seemed great for the price. But with two different dimmable LED lights there was a flicker at the lower setting. The only way to eliminate it was to increase the brightness on the adjustment. But then there wasn't much of a difference between high setting and low setting.

Surprisingly good product. I've been using the $23 switches for a while and decided to try these as a value option to save money. While they don't feel as sturdy and premium, they are damn near close. Strong recommendation.
