Product is beautiful

Everything matched well. No instructions came with the tonneau top at all. We used youtube videos to help. As for customer service of this company: it was horrible. Ordered on July24th. Got it September 4th. We had to drive 115 miles to get it. Everytime I called they gave me different dates. I would not buy from them again. The product itself was good quality is about the only positive I can say.

UnderCover tonneau

Purchased the color matched Undercover Elite LX tonneau cover and I'm very pleased. The color match is spot on, and the fit and finish are excellent. The inside is finished with material that matches the BedRug I installed and matched perfectly. Installation is simple and fast, measure for the four brackets, tighten down 8 bolts, snap on the pistons, then adjust the latches for the locks. Very easy and takes around 30 minutes. I think it's a little on the high side for price, but that's how I feel about EVERYTHING today. Even with the price, would I buy it again - yes!! I previously owned another major brand tonneau on my last truck and this UnderCover tonneau blows that brand away.
