This is my 3rd order for this product and in each case the board when properly connected DOES NOT WORK. The problem is the Op-Amp. When the OP-Amp is properly installed, the unit does not work. It has to be physically removed and then the unit is fine It's not that this is unacceptable, but it means the people who are selling this unit never even bothered to test it out!!! Increible!
