Review on Emerson 5D51 35 Universal Replacement Control by Dominic Webb

This replacement control is not worth the purchase. As my tests showed, it is unreliable and faulty which caused major setbacks in my Industrial and Scientific work... The only pro I can mention is that it's reasonably priced. However, the cons outweigh the pros as it caused me so much frustration and time wastage. I would look for a different brand or product altogether when it comes to Electrical Controls & Indicators in Industrial Electrical..
