Excellent product
Bought this item it actually came before the due date I couldnt find a better priced item like this. It was a perfect fit and it was just as described online. There were no flaws in design. after I removed the old unit I compared them side by side before installing to recheck for flaws and there were none I would recommend this product all thumbs up.
