Overall I am impressed with the appearance and quality. Box was damaged but contents unharmed. It was packaged in some flimsy foam and I would think Bakflip could figure out how to protect it better... who knows how the freight companies handle big heavy items. Install was not bad at all. Need a helper at times but it can be done alone. Be prepared to spend some time adjusting and getting the fit just right. Don't peel the backing from the foam until you are sure you like everything... that will avoid peeling it back up to make adjustments. They need to provide some way to attach the drain tubes so they don't flop around. Overall appearance is fantastic and I like the flush fit that matches perfectly to the truck. Now I notice other brands in other trucks and none of them compares to this.

This is a very well-built product! Took two hours to assemble but I took my time because I wanted it to fit perfectly, and it does!

It's a quality item no doubt. Finished product looks quality and will protect your stuff. The fact that you can close your gate without crushing your Tonneau cover makes this first rate. Forget about soft tops a key can tare it vulnerable to theft and you could lose all your important stuff. This Bakflip MX4 looks awesome and functions as promised.

The BakFlip MX4 is great at this point. I haven't had it long enough to see if it leaks or if there any other issues. Based on the quality so far, I'm impressed. It was easy to install. I really like the look and functionality of it.

Far from water tight. Cover is a tad short for my 6.5 foot bed to adequately cover the tailgate.

I'm a 60 year old man and did the install by myself. The directions were very well written and so anyone can follow. To adjust this was the easiest cover I have ever installed. The fit was extraordinary.

Wife and I took our time to install with constant interruptions. Instructions were good. Diagrams could be improved. Impressed with the quality and looks. Some adjustment may be needed later but should not be a problem. I would buy again and would recommend.
