“Outstanding, had them installed by a Cadillac dealer, works great.”
“Detailed, easy to follow instructions. Product is great quality. Tried (unsuccessfully) to install a competitive product, and the difference in the product is quite noticeable. Customer service was personal, responsive, better than most. Will definitely buy from Check Corp again. “
“Orders are always taken, filled and shipped on time. Check Corporation is a good source of information on cars…Warranties are always handled professionally… Sales makes sure we always have information to sell product.”
