Salvajor 3-HP Basic Unit Food Waste Disposer

My problem is only with the Salvajor product. I do not have any issues with Amazon or any other company selling this product. this is only a buyers beware... do your research.I have purchased 2 of the 3hp commerial units 208 volt model # 300 trying to save money by using the the old Electric panel. and did save money upfront.I don't know how old the first one was, but the two that I purchased were both profrssional installed and lasted less than 4 years each. I just got the quote of $3930.00 for the disposal and $436.00 for shipping. plus install.total over $5200.I will never let anyone buy this product I am not sure what brand I will buy yet but I will spend the money and replace the electric panel too.
