We purchased a Pride lift chair from our local hospital supply store. When the original control failed, we requested the store repair it. Although a representative came out and ordered a control, it was the wrong control. We were told we were on our own. We contracted the manufacturer Pride, who referred us to a couple of different sources. One was too distant, and the other wouldn't repair a Pride chair they hadn't sold. We googled Monster Scooter Parts and ordered this control with the best information we possessed, albeit sketchy. A family member installed the new control, and it works like a charm after months of delay. We're ordering a second control for backup.
