Bought this to replace a no name brand I bought on eBay. The plastic window guide broke on the no name brand in about 5 uses within a 3 month period. Tested the Dorman and works smoothly and quietly. Had surpassed 5 uses now compared to the no brand name. I have used other Dorman products before and all have been of good quality. Don’t waste your $ in the cheap brands and go with Dorman.
