"I recently ordered a replacement pulley for my weight machine, carefully checking the model and part number to make sure there was no error. I received the pulley, but could not use it since the center hole was a smaller diameter than the original part and the mounting bolt would not fit through it. I called and they required a picture of the model and serial number plate of the machine, a picture of the original and replacement part with scale provided, and a diagram of where the part mounted on the machine. Fortunately I had all those and it could easily be seen from the photos that the original hole was a 7/16” and the replacement was 3/8”. The first reply I got from their “research team was that the diameter of the pulley and the cable guide for the replacement part was the same as the original. I reiterated that it was the central hole diameter that was different, not the pulley diameter. They then came back and said that their “research team” had determined that the original part indeed had a center hole diameter of 3/8” when from the pictures I had sent it clearly did not. They said I could return the part, but would be charged a $20 restocking fee. I then sent a video of the bolt going through the original part but not through their replacement and said I was sending the part back and expected a full refund since it was their error or I would contact my credit card company. We’ll see what happens... By the way, they were charging over $50 for a part I found later on Amazon for $14.95. Steer clear of these losers"
