Sometimes, the best experiences are those that don't quite turn out as you hoped. After looking for a compatible control board for our 31-year old GE XL44 oven, we found one with Apex that we hoped would be compatible. After installation, we got an error, and -- having purchased the additional warranty -- I returned the control board with a letter explaining what happened. I received a refund without any problems. Quick delivery, great, responsive communication, and really good people. There's a reason this company is so highly rated. I recommend Apex Used Appliance Control Boards and will use them again if the need arises.
