This part was shipped quickly and came exactly as described. My son and husband had no problem replacing our broken regulator with this new one. In no time at all we were back in business with a repaired rear window!!

I bought the cheapest unit I could find. I paid about $30 other sites were $100 and up the dealer wanted $180. so I was expecting a cheaper product and expecting to modify it to make it fit. To my surprise the window regulator looked better built than the OEM unit. And the install was a perfect fit. I had zero problems or complaints

I had it installed about two months ago, with no problems. I hope it doesn't break. I like the price, including the install it was 1/3rd the cost of quote from BMW dealer.

installed quite simple to do ,but lasted 4 months now need another one with same problem the gears are plastic and they shear easily regular use is too much abuse. ordering the direct replacement at a higher price. the other one comes with BMW seal on it when replaced on opposite side and has lasted over a year now.

This product was reasonably priced (about half the cost of what the dealer charges for OEM part) and fit as good as the original regulator it replaced. Quality does not seem to be quite as good as OEM part but for half the price it was worth giving a try. I have had this product in my car for about a month and it is working well. So far so good.

BMW regulators are a known problem so I figured why pay double for the same bad regulator from the factory. I figured at almost half the price for this replacement brand that it was worth a try...it was identical in appearance and it might even have some components that are better than the factory piece.

The factory regulators are a known problem and the replacement from the factory is the same (not an upgraded verion)...this aftermarket item is definately as good if not a better quality and is almost half the price...
