Review on 🔥 Efficient Heating Control: Omix-Ada 17903.04 Heater Switch for Reliable Performance by Mike Ogunlana

I gave 2 stars because it gave me a speed more than the original rear derailleur, doesn't work - this is a high setting that worked before I changed it. The switch went in easily but was cheaply made. It seems convoluted if you use a selector (cheap). I can't figure out how to contact the company to see if they will send me a replacement and after reading all the reviews many people have problems with this product.
