I got it for moving. I tried it on heavy boxes and it did the job without any issue. I didn’t test 100 kilos, but it handled an electric stove (on a route without stairs). The negatives: The loading surface is small and slippery. Also, the wheels are small and not convenient for stairs. For a flat surface, it’s just right. Folded, it takes up little space. It comes with a securing strap. It might be useful for transporting beach equipment, although I’m afraid the wheels will sink into the sand. I’ll come back with an update.

I bought the 100 kg one which has a somewhat larger base. It seems very sturdy and it's not particularly heavy. The wheels are durable. I highly recommend it.

For its quality, its price (~€23) is laughable. Sturdy construction with stable movement during transport. Up to 50 kg it doesn't struggle at all

the best 20 euros I have spent.
Used for moving. If it had a slightly larger base it would be a 5. It folds and stores very easily and doesn't take up space.

Very good quality, sturdy and flexible for bulky and heavy transports. I used it up to about 80 kilos and it did its job perfectly. I highly recommend it.

I was very pleasantly surprised as it is a very sturdy construction. Also, the "base" is metallic. If it were a bit bigger, it would be perfect. It folds very easily. I am attaching photos where you can see that it holds a sack of wood with the help of the "octopus" which is included in the package.

Amazing trolley. It made things so much easier for me, I have the 100kg one, it easily lifts 60 (I haven't tried more but I'm not worried, it's very well built), it also has two very good straps, it goes up stairs, folds and becomes flat and fits in the trunk without taking up space. Highly recommended.

Good, quality, aesthetically pleasing as a construction and compact when folded. I bought it because it has a high load-carrying capacity (that's what the specifications say) and because it has a fairly large platform compared to the competition. It folds and unfolds without problems and the only criticism is its weight. At the moment I am writing, it is working and carrying various loads of different dimensions, weights, and sizes without any issue at all.

Functional, but the horizontal section should be a bit wider because the large boxes fall off

Very good and quality. I have moved a washer-dryer and it has held up. When it closes, it takes up no space at all and is very easy to carry with its handle. It opens very easily, just with the foot. It requires a little caution when it is open and not loaded, sometimes it closes.

Soon...VERY good for its money!!! 22€

The truth is that I was expecting something silly and fake...but I needed a trolley for small jobs!
And when I received it...and held it, the first thing that impressed me was its weight!!!!
It's not fake...I don't know about 60kg...but up to 30kg that I have reached, it is quite stable and without any issue!
And it's so small when you fold it, that it really doesn't look bulky inside the car!
[Now as for how much it can withstand...we will see!]
