Car Rooftop Cargo Carrier - 21 Cubic Feet, 100% Waterproof Heavy Duty 840D Car Roof Bag for All Vehicles with/Without Racks - Anti-Slip Mat, 6 Door Hooks, Storage Bag, 2 Extra Straps

Pros - I didn't have to install a luggage rack (but that's for all removable racks) Cons - 1- quality of the strap is so inferior the buckel snapped when I was testing the rack on the floor.. thank God I didn't mount it 2 - no door hooks given which means i have to install a railing or buy door hooks separately which cost around 4k separately 3 - The stitching around the carrier is really low quality.. i put some bags during testing and tried to zip it. The zip was stretched and could separate from the bag if i applied more pressure.. remember that's what will happen if we mount it.. So overall not worth it.. there are other products that will give you accessories to support your installation while this comes in a below standard plastic bag..

Worst Quality,When i received it no accessories which is mentioned.Would not recommend to anyone..It is not worth even 1500

We went from Wisconsin to Arkansas and not one problem it held up great and would buy it again it also has tons of room. Wind resistance and installation was very easy.

Worked well with copious amount fitting in the Bag, completely waterproof as we travelled 500km in very heavy rain without any leakage

Failed attachment point.

When it came is was huge. It was much larger than I had realized. Which is great imo. It did awesome. We drove from Utah to upper Michigan. 3000 miles round trip. In wind and snow and rain. Held up fantastically. No shifted items, nothing was wet etc. Infact I have been driving around with it on my van since we got home too. It was off while we were in Michigan. It goes on rather easy. I had to get a step stool to reach the center to pack it. I'm short. The zipper is very strong. The Velcro is almost annoyingly strong. It definitely does it's job. It hooks right up under the rubber weather strip for the vehicle doors. We fastened the 4 side hooks to the doors. But I did purchase some suction cup attachments separately. We hooked the two front and two back straps to those. Nothing budged. I do not have a roof rack, so idk how it works in rack, but flat roof was perfect. Folds right back down to fit in the bag it came with. We did notice a decline in gas mileage (to be expected). But when we were driving around 70 it did much better (there are speeds on the highway we too that was 80mph, where we noticed a big drop in gas mileage) The short of it. Its fantastic, did it's job very well. Would highly recommend.

Loved the bag and it's size but it took only 2 uses for it to start having big cracks. Useless after that
