Sent in Pcb boards for repair and when they were returned to me one of the touch screen boards shorted out The PCB board on a printer. not one of the three items I sent in worked. I sent them back for warrenty repair and recieved one of the PCB boards back like two months later a ong with a invoice and it diidnt work. I am still trying to get Radwell to credit me for the Burnt out PCB board. I sent it in for them to look at it and they cannot fix it. So I am out $2,000 for a PCB board because of their negligence. I have been going back and forth with this company for months. they do not return emails and they will just ignore you if you don't follow up with them.
