Most Popular Roof Box for Mazda 3

I can see why people consider the box a bit flimsy, especially when you do not have it secured to the car and nothing is inside. That’s normal. For this to weigh 34 lbs and yet to be wall sturdy and provide waterproof conditions that the bag cannot, it has to be lightweight. Once we attached it to the car at 4 points, it wasn’t going anywhere and was instantly sturdy. I wouldn’t roughhouse with the locks or opening it up and down with force however. Also, 14 cu for a sedan is plenty. Anything larger and you are looking to push the limits.

Bought this box to hold camping gear while on a cross country road trip. You can put quite a bit of stuff in it. Held securely to roof rack and kept contents dry. I liked that the key could not be removed if lid wasn’t completely closed. Minimal affect on gas milage.

Excellent car top carrier (not that I've had many to compare it to). Easy to install and remove, sturdy, and fits well on our Toyota Siena. Opening it is a little tricky, as sometimes the top sticks to the bottom a bit. Adds a lot of extra storage to our car, great for when we go camping. Great experience with etrailer.

Excellent roomy cargo box. My wife’s luggage even fit (see photo). Fit the top of my Forester like it was meant to be there and the hatch opens without obstruction. Great shipping by etrailer.com via Estes freight shipping (almost overkill on shipping).

After a year of dependable use the SportRack Vista XL Cargo Box continues to perform to my needs, wants, and expectations. The 2 attributes that shine the most are ease of access/cargo loading (rear access vs. side) and ease of off/on (lightweight and access to the U-bolt hardware). While the overall quality of the materials and hardware are not quite "Excellent", they're darn close. For my needs I'm very happy with this cargo box and the price point makes it a better option the the more expensive brands. It may not be as cool and groovy as a Th*** or Yak*** box but it gets the job done.

The Roof Box was as described and fit great -- Nice. Shipping however was not good, trucker dropped it and the skid at the foot of the driveway -- It looked like it had been crushed and dropped. There was some slight damage, but we accepted it as complaining would be more trouble than it is worth. E Trailer should vet their carriers better -- no care taken with this shipment.

my rooftop carrier! It was perfect for our golf clubs. etrailer was wonderful. Great communication and it arrived on expected date.

It was what I expected with a feature that I didn't expect. The quick mounting clamps make it very easy to attach.

Perfect fit on my 2014 Jetta Sportwagen. Lets me accomodate my lighter weight camping gear and leave the heavier stuff in the car. Very secure and aerodynamic and had very little impact on my mileage. My only issue was I could never find the serial number on my rocketbox.

I've taken one 1500 mile trip so far with the Yakima RocketBox Pro 14 mounted on my RAV4. I found the box to be quiet and not to have much impact on gas mileage. I lost maybe 1 mpg with it mounted to my flush mounted Whisperbars. I drove through some very heavy rain and had a minimal amount of water inside under a thin rubber mat I had placed on the bottom of the box; none on my luggage got wet. This box works great to give me more carrying capacity when traveling with my two crated Dobermans.

Amazing box. We added it to our lambo for rallies. Used sea sucker mounts.

So I really needed something that was both small but still had lots of room to fit on top of my ND Rf Miata and this was the perfect size. So the method to attach it is quick and pretty easy and I'm able to do it myself without really needing a second pair of hands which is convenient.

My original INNO box I bought back in 2013 and during a wind event in Colorado, it sounded like a Teradactyl landed on my car and ripped open the top. I spent a month researching boxes and still chose the INNO. This is the new and improved version of what I had before. I like the metal clamps that hold it onto the crossbars, instead of the plastic claws on the former. It also is just a titch taller, longer, and wider that will be an asset with skis during the winter and camping equipment during the summer.

I use this box about twice a year when I drive from Missouri to Florida and back. It lets me pack most of our stuff on the roof so we can keep the 3rd row up and fit 4 adults and 3 dogs comfortably for the drive. The only thing I would change is The box has hand knobs with nuts inside them and the nuts fall out. Easy to put back in but it'd be better if they just didn't fall out.

I just ordered my 2nd cargo box from e- trailer. I really like this box and have ran it on multiple vehicles. Definitely recommend

This was a great experience from start to finish. etrailer: After placing the order, I called regarding shipping and quickly got the answer to my question. The box shipped by ground freight, and arrived almost a week before the original scheduled delivery date. The Rhino arrived perfect with protective wrap, and all the required parts. Rhino Rack: This thing is awesome. Unless you jump up into the $1000+ price point, your rooftop carrier options are limited. My two requirements were to fit my skis (181 & 183 cm) and to allow my tailgate to open fully. The Rhino delivered! Bonus that both baby strollers fit as well (Instep baby trailer and Vista Uppababy). Only a week in, but so far the Rhino box and MasterFit clamps seem solid. The ratchet/locking mechanism on the clamps is just ok, you don't have to twist too hard to over power the lock or feel like you are stripping something internally. The hinges are beefy, but don't take up a ton of storage space. It opens from both sides, and you can't remove the key unless it's locked, which is nice for those of us that don't enjoy picking up our stuff on the highway. Also, if you're like me and spent way too much time on mr-box.com, you'll be pleased to know that this thing doesn't look lame. It's pretty sleek, somewhat low profile, with a touch of Euro. It's not too wide, even on the narrow rails of the A4 Allroad there's extra bar space. I could probably squeeze an upright kayak rack, small ski pinchers, or for the ten of us in the world that own RoadShowers...the RoadShower 4 fits no problem. I definitely recommend a Rhino from etrailer.

This is a great car-top carrier. It is light and easy to install and move around. The opening and locking mechanisms also work well. I drove 5 hours with it in the rain and no moisture made it inside. eTrailer was also great when ordering. The freight company lost the first one and eTrailer simply sent me a replacement. Great company to work with.

Great product from a great company I bought this rooftop box for my daughter last year when she moved from Georgia to Oregon. It held well even in ran and snow. This is my second Thule rooftop box. I wish I had bought the first one from etrailer. They have great prices and great customer service.
