Really love this cart. It is very easy to set up for me. I am using it to haul a lot of various shaped boxes and musical instruments to a camp and having the long configuration with the handles up is great for squeezing in a ton of stuff. Seems very sturdy. I have also used it shorter and long with one handle down, which was super great to have as an option. I will mostly be using this to haul music gear into gigs and it should be great for that. I was worried this model (r6rt) would be too heavy but its not. It really folds up small. So to sum up, this is a great purchase, very happy with it.

I recently opened a candy store in a mall and needed to haul lots of stuff from my home to the store, including almost 800 pounds of Jelly Belly products. This cart handled it all beautifully (not all at once of course). I recently moved that same amount of candy from my car into the store when a freight delivery couldn't get there when I needed it. I keep this cart in the trunk of my car for moving various items in and out. As suggested elsewhere, I cut a piece of particle board to use as a base for moving smaller boxes; big boxes can just sit on the frame. I'm still amazed by the brilliant engineering of its design. You have to use it to appreciate it. Of the hundreds of dollars I've spent on accessories for the store, this is definitely the most useful. Highly recommended.

This review is for the R6RT cart, and I have to say that this is one of the best purchases I have ever made.As a regularly gigging musician (drummer) I spent years hauling in my kit a couple pieces at a time, constantly locking and unlocking the car and making multiple trips. Eventually I grew wise to the ways of the hand truck and purchased an industrial grade one from a local hardware store. Although it properly fit my equipment it was large and heavy and took up too much space in my SUV to be practical.

Enter the R6RT cart from Rock N Roller. This thing was a god send, and has made the worst part of being a musician (load in/load out) so much more tolerable, and saves me a huge amount of time during set up. I play on a small "portable" kit and the R6RT fits all of my equipment snugly and easily, and breaks down to a convenient size that fits perfectly in the trunk of my car. The lightweight aspect of this cart is another huge plus. I also love the "no flat" wheels (a problem in the past with industrial hand trucks) which slide smoothly over most surfaces including grass and small rocks while remaining stable.

I would recommend this cart 1000x over to any musician that has gear to haul. For anyone thinking of buying this cart, so not hesitate. However, the R6RT fits my small drumset perfectly, but anyone with a "normal" size kit will definitely need a larger cart; but if the R6RT is anything to go by, the bigger carts should be up to the same incredible standard.

Nice cart with good sized wheels that almost (but not quite) feel like rubber wheels (which i'd rather have had, but i'm ok with their plastic ones). Easy to set up and well built. Some complaints:

1. Quality control is not very good - you're supposed to put on a plastic washer on the axle before you put the large rear wheels on, then drop a cotter pin through the hole at the end to lock the wheel on- but with the plastic washer on both sides, there's a quarter inch of space where the axle rod sticks through the wheel, so it's easy to reach in and drop the pin in the pre-drilled hole for it. On the other side though, only a millimeter or 2 of the hole is visible, with the rest being covered by the yellow wheel mount... so the pin won't fit. I had to remove the washer to get enough room where i could put the pin in. It's obvious the post was welded a quarter of an inch too far to one end.
2. Would have liked pre drilled holes i the bottom of the frame, so you could extend and lock the length you want easier. The way it looks like, you can only do that when fully extended, otherwise you have to use the wing nut to tighten it to the frame, instead of the pre drilled holes in the fully closed or fully extended position.

Also, this thing cheaps EASILY. Paint came off hen using a bungie cord with *plastic* hooks that wasn't even on tightly. When putting down the handles, they just barely touched each other and the paint came off. Very very poorly painted. If you buy this cart, also buy a bottle of touch of paint, because you'll need it.

I did like the grip tape on the frame- it's not too rough where it will damage anything, but gives just enough grip so nothing slides off. The rounded "stair climber" feature is useless, unless you want to grind the black paint right off of your cart.

I also with one side of the rail could extend higher, as if you're a taller person, you'll have to bend over to be able to reach the handle. But a good cart on the whole that hopefully will be improved down the road. If you are taller than 5'6", you won't be able to push the cart unless you lean over to get to the handle- pulling the cart from the front is the only way you can manage, and both not pleasant to do.

From the reviews i've read on here, there is no such thing as customer support, and they will not contact you back. The only reason i bought this cart is because there wasn't another cart similar to what i needed by another company.

Update (4/17/2017)
I've only used this cart 3 times, each very gently, and i still end up with chipped paint off this thing, every single time. If you order this cart, you'll also want to order a bottle of black touch up paint, because you'll need it - A LOT.

The cotter pins used to fasten the lower part of the handle assembly to the base of the cart wan't bent back enough, creating very sharp edges that caught on my camera bags. Luckily i spotted it sticking into the bag and pulled it away before it had a chance to damage and tear the bag. The company really should use another type of cotter pin that doesn't create this situation, or have more quality control over their product.

Notices that pulling the frame rails apart to make room for gear, shreds the frame paint off in an instant, exposing patches of bare metal. Another bad design flaw.

The sticker advertising the company started peeling off the cart frame within a week of purchase just sitting in my room. I pulled both off to spare anyone from knowing where this cart came from. (Sorry RocknRoller, your cart rolls, but it definitely does NOT rock).

Easy to put together (you need a wrench or some sort of multi-tool) by yourself. It's super versatile. It looks very nice as well. I even got compliments on it from a number of strangers who saw me carting around things with it!

Just be sure to pull it by the end with the small wheels. I don't know why but people want to pull it from the large wheels, which are supposed to be in the back. It's much easier - and how you're supposed to operate it - by pulling with small pivoting wheels in the front.
