The installation went smoothly, and the product shows all the promise I can hope for at this point for being a great addition to my F150. Before installing, I recommend viewing the online video installation instructions - they are quite good.

I did it by my lonesome, but another set of moderately-strong hands would have sped the process. My ONLY real issue is that the belt buckle hardware had buckle and screw fails on one side of the installation. I need to contact BAK to please send replacements. Looks good, weather-tight, so far, This cover has a "kinda-pricey-but-worth-it" sorta vibe.

Delivery was fast But when I opened it up one of the rails weatherstripping was wrapped around the rail stuck to all the plastic had to peel it all apart and apply the weatherstripping to the rail myself. I guess who packaged it was close to getting off work and wanted to get home but was quick to install easy.

The installation went well, looks nice. I would give a better rating but had a corner of my cover cracked. It was like that when I removed it out of the shipping box. I used gorilla glue and duct tape to hold it together. Wondering if i can get a replacement piece. Also the weatherstrip on one side has a hump, I used a hairdryer and is still showing.

Took longer to install than I thought it would, install wasn't difficult just time consuming. It does leak a bit but not enough to be a problem. Works well and looks great.

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.

I like how it looks and operates but a couple of problems encountered. Drop in bed liner had to be cut/trimmed at cab end to facilitate the installation, otherwise rails were too long. Also the drains on the top are too long to allow for drain hoses to be installed and route to truck drain openings. The top drain ended at the same level as the truck bed drain opening ended (kinking drain hoses). Needs a modification or a actual molded drain hose that fits truck openings. I have noticed leaking during rain but have not had opportunity to discern as to exactly where leak is.

The Bakflip Mx4 looks awesome on the truck! It was easy to install -- instructions were easy to follow and I had everything I needed. I did take a little extra time to ensure that the cover was properly aligned on the rails to cover for water tightness. I haven't tested it in the rain or snow yet but I did take it to the car wash and there were no leaks. Love it!

My only concern was the sliding latches could be deeper and that there were none on the second panel from the rear. Also drawing were a little odd. They could be more detailed. Overlap of seal on sides and front could be extended l/4 inch on sides and l/2 inch on front.

Overall looks like a good product. Had to make some adjustments to the latching mechanism that locks the cover down to the rails because they were set a bit too far inboard and the panels would not reliably lick down. Also, the holes for the attach bolts had to be opened up. I made all the modifications myself with a drill and it still only took about 45 minutes to install.

Just love the look of our truck now. It is super cool to have this secure cover, so we can do our shopping without having to run home and drop off products so they won't be taken. We agree that the cover makes our ride in the truck quieter, a bonus we didn't expect.

Not difficult to install. Took a little over an hour. No help needed. I routed the drains behind the Berliner with no drilling. Just had to trim the liner for the rails to fit. Used a knife. Fits good. Hopefully it doesn't leak! We will see.
