[Aluminum] just bought my 2nd one... this cart is great, wrap it up and check it at the airport, make sure you get the shelf. also be sure to get the version with the solid tires. plus the lip folds down and you can roll long items like sliders or stands.

[16 lb / 7.25 kg] very strong, very good packaging from the factory. Took about 2 months from ordering to delivery

[25.5 lb] Extremely well designed heavy duty cart. I bought this cart on the recommendation of a friend after overloading and breaking my last cart. While weighing a lot the cart is super smooth and holds a ton of gear.

[16 lb / 7.25 kg] I always hated the shaky flimsy feeling of the other carts out there. This one's SOLID... well made, locks together rigid and rolls well. Can easily hold more weight than you'd ever be able to stack on it. And in the short mode, rolls comfortably into small elevators. It's as powerful as a Magliner JR but collapses down smaller. Only wish Grip nGaff made a stands bag to fit this one, although some of the ones made for thee RocknRoller might fit.

[25.5 lb] I've borrowed and used a ton of these handcarts over the years. It was finally time to buy my own after a few other brands' handcarts failed under my abuse. This thing is built to take a beating and not skip a beat. It is heavier than every other competitor option but it's compact size and flexibility well makes up for that! The only thing that I wish this handcart had would be more options for accessories. Aside from the easy-to-find decks, there aren't many for accessories so be prepared to DIY your solutions for customizing this rig. Piece of advise... just buy it!

[200 lb / 90 kg] As someone who owns numerous carts for film production (converted MagLiners, Rubbermaids, C Stand Cart etc) this is an incredible cart for the price. Some people reading this may be thinking, This is affordable? but in the world of high quality carts this is affordable. (Converted Magliners run $1500-2000)
This cart is heavy duty, the wheels handle downtown sidewalks with ease and its pretty darn quiet when rolling along. It can handle a lot of weight. I load this thing up with Apple Boxes, Milk Crates full of grip gear, half a dozen sandbags and C Stands and its no sweat for this thing. 

Its very flexible with how many options there are for carting long items like large flight cases (think 4ft Kino Kits or SkyPanel S60s) to smaller items. Industry standard Milk Crates fit perfectly. The locking wheels work better than most. One Note: It is a heavy cart to lift.

It is the most compact cart Ive ever seen in its category of strength. It folds down so small.

This brings me to the one caveat of this cart.

Two words: Pinch points. You will need to make sure you fully understand this cart and how to properly collapse it. You will also need to make sure no one else collapses this cart unless properly trained to do so. This sounds like such a silly statement but this cart will seriously injure your hand/fingers if you fold it incorrectly. Ive had two close calls. Out of habit from other foldable carts I folded it incorrectly. I only say this as a safety precaution, the cart is still 100% worth buying. If you need an extremely strong cart but have a smaller vehicle this is the best option Ive ever seen out there. The Rock n Rollers arent even close when it comes to the strength of this cart. Ill try and add photos to this review later.

[16 lb / 7.25 kg] This cart is fantastic.
I am a cinematographer often traveling with 4-9 pieces of luggage. I live in NYC and do not have a car, so all of my gear is relatively compact, and this cart fits right in.

As much as I wanted an Inovativ, and have had great experiences with them, this was absolutely the right choice for me.

This cart fits into small car spaces and fits into my 80sq foot office without taking too much space. It opens and closes in seconds, far more useful than the Inovativ setup for my needs. I strictly use this for moving equipment from A to B. The shelves do seem cumbersome and I suppose they would only make sense with my own vehicle to store them in. Right now I am happy with the dolly as is. The construction is impressive, it's a very solid piece of equipment snd I am much happier with this cart opposed to the next competitor, Rock n Roller. I waited about a month on back order and would never look back. My next cart will be an Inovativ, once my workflow allows me the space for it.

[200 lb / 90 kg] This is actually our 2nd Kartmaster, the first one is almost 20 years old, and still works great. We just needed another one to haul more gear, any R&R competitor cart is really no comparison. Once you learn the couple places NOT to put your fingers when folding it up, you, too will love this cart for decades.

[200 lb / 90 kg] Great cart. Folds up fairly compact, doubles as a cart or hand truck. The optional shelving add on is a must for carrying more gear. The tires are awesome too.

[200 lb / 90 kg] This thing is amazing. I fly with it everywhere and take it on every shoot. Heavy, but has your back!
