Very pleased with everything about the transaction except for the instructions which are inadequate. Videos on YouTube are much better. It took 1.75 hours to install by myself on my 2019 Honda Ridgeline.

Excellent product, I highly recommend it. Amazing online service, delivery on time, parts complete, good quality. Just a couple suggestions, you can add a link to a Installation video, so it is easier to follow. Also, the metal clamp does not go all the way up, so I do not know if that is something that will affect the product the a long term, so mentioning this possibility will be good to guide the user. Thanks a lot!

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.

Easy to install. Fits like a glove, I really like the low profile of the cover. Quality seals to keep water out. Great product. I would recommend this truck cover to anyone. The locking device by the tail gate is easy to break into. Just lift up on the cover and use a wire with a small hook on it to hook the cable and pull it to open. Other then that great cover. Looks good on my Raptor too.

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.

Overall the BAK MX4 is a really great product. My reservation is with the installation instructions and the seal at the tailgate. I have a 2019 Honda Ridgeline which requires additional side rails due to the bed design. I had to watch a YouTube video to really understand the installation instructions. Also, the seal at the tailgate leaves a 1/8 inch gap on the right side. Otherwise, this is a super product.
