by fromThule cargo box We sold our truck recently and decided a cargo box for the top of the car would be a good idea for extra storage. After looking at quite a few options we decided on this box because when installed on our car, it was the only one that would still fit in our garage. The others are only a couple inches taller at most, but I didn't want to rip it off pulling into the garage, or park outside. Install was very easy. It took maybe 5 minutes on a Thule aftermarket rack system. I like the sleekness of it and the fact it is a bit lower than others. I would've given it 5 stars except every time we go over a bump at low speed we hear something banging around inside the box. Come to find out the hinges are installed an a ball mount system and are way too flexible so they move back and forth and hit the ends of the box(when stopping or pulling in the driveway). I may find a way to MacGyver the thing so it quits rattling. Other than the hinge issue, I really like this box.

by fromGreat product-can't wait to use it again We used it for the first time driving from WI to SD to carry our camping gear. We used our four door sedan with a Thule roof rack. The cargo box attached easily and is extremely simple to secure to any shape roof rack bars. It worked well and as expected and gave us a lot more usable space. We really liked the ability to access the contents from either side. During the trip, we placed items that became dirty in it so the car trunk could remain clean. It was difficult to lock if slightly over packed with items like sleeping bags and pillows that are easy to compress even though the cargo box closed and sealed completely without any problems. When opening the top cover, both the front and rear needed to be opened at the same time or one end sticks keeping it from opening. This was easy to solve by closing it slightly to equal out opening it front to rear. The cargo box halves are a bit flimsy when opened, so care should be used when loading and unloading. When closed and locked, it’s solid. Our vehicle gas mileage was affected a little as expected, but the fuel cost we saved by not driving our full size SUV paid for the cargo box on this trip. Bottom line, great product! We were very impressed by its performance. Can't wait to use it again.

by fromGood box, good price I got this for a cross country move (NC to WA). We needed a bit more space to pack what we needed while waiting for the movers to arrive. I was going to get the Skybox 12 but this was all they had at the store, so I picked this up accordingly. Overall, the box is good and as advertised. The capacity is great. The ability to open from both sides and not be able to lock unless all of the latches are in place is a very nice feature. I am happy with my purchase, and will continue to use this box all the time, but I will point out a couple cons for you to look out for-- The box is LONG (which is the point, because I wanted to used it for skis/ snowboards in the winter), but as a result on my small Volvo S40 the front sticks way out past the front of the car. This killed our gas mileage (normally ~32 on the interstate, ended at ~25 over 2900 miles). I think on top of a longer car or SUV the gas mileage will not really be affected, but in this case, it was. But that is the nature of the beast I suppose. The construction seems to be adequate, but I think ultimately this will not last "forever." There is very little extra structure other than the plastic box. I would've liked to see an all aluminum locking mechanism/ hinges as well as some aluminum stabilizers running front to back. The box bounced a little on the front end, nothing major but being a bit more rigid would helped the mileage issue above. Finally, the seal of the box leaves some to be desired. When we finally opened it up quite a few splattered bugs had slipped in there. We were lucky that it didn't really rain the whole trip, but if a whole wasp can slip in there, I have a hard time believing that it is going to be very water proof. This is nothing a little weather stripping on the front edge won't cure, but that should be built-in so it doesn't interfere with closing the box. Overall, again, if you need a box, this is a good option (esp if you have one of the REI 20% coupons).

by fromGreat product, but not good fit. I used the Ascent 1100 for a camping trip with friends on top of my Jeep Cherokee. It fitted easily 4 sleeping beds, sleepings pads, large tent and two camping chairs. As well as some additional small gear. Although the Thule fitting guide claims that this roofbox also fits on an Audi A4 Avant, it simply does not. I don't consider the fact that you can't open the trunk completely as a good "fit". Minus points for Thule for not being accurate. If you have a bigger car: no problems, good product!

by fromGreat solution for winter spots gear After putting a great amount of time into research I settled on this box due to the size and dimensions. The narrow width fits on my crossbars leaving room to keep the roof bike rack mounted, and the length fits skis and poles and snowboards comfortably while allowing my rear hatch door to open fully. It was the perfect solution for getting gear for 3 kids and 1 adult into my car, since skis and boards dont fit into the trunk without the seat reclined. I was able to fit 3 snowboards, 1 pair of skis and poles with room at the front and back. Note, I dont think 4 snowboards fit, at least I can't. There is plenty of room to tuck sleeping bags, boots, jackets, and other small squishy items all around the equipment. There ARE tie down straps included that attached to the mounting hardware on the inside to keep items from moving around, but when the box is not packed full, it does make some noise on the car. Also, my gas mileage was slightly reduced and on the BMW, the drag on the roof is definitely noticeable especially at highway speeds. Overall I like this box and I am definitely keeping it on the car all winter!

by fromFunctions beautifully I used the Thule website to see if this fits on my 2012 Outback and it says it does but, it was wrong. When the back is opened the third brake light will rub on the back of the box and cause the box to flex a bit. The box flexed enough it didn't put too much stress on the clamping device. Mounting to car was easy once location was set. I have more confidence with the clamping device after my first trip. I would like to see more hold down points inside the box. I am keeping the box because it allows me to keep it on when entering or exiting my garage. No noticeable sound increase when driving at 70mph. It does catch side wind more than without it. I still love it and will recommend the product to others.

by fromLooks Great and swallows up your gear This top box looks great on top of our 4X4 and easily swallows all the extra gear we take when we go off camping or head to the cabin in the mountains. It fits on very easily to the factory roof bars and the double sided opening has found to be well useful.
