Fantastic product!
I purchased the RoofBag for a road trip for my family of 5. My Kia Sorrento doesn't have a roof rack so this seemed like it would work well. I'm 5'2" and was able to position it on the roof, load it, tighten the straps and unload without any assistance. It would be easier if you had one person on each side, but I loved that I was able to do it all by myself without assistance. It did rain during our trip and a bit of water did run down the straps into the vehicle, but our luggage stayed completely dry. It wasn't enough to really worry about, but I did want to mention it. I did misplace one of the straps and had to purchase a spare separately which was a bit pricey. All in all, this was a great purchase and I would highly recommend this product!
