Gravity CART M 01 B

I've had this cart for 8 months now, and it serves me well. But, there was a problem with the 2 knobs used to tighten the tubes that slide into each other. The plastic on the knobs is very soft and if you want to properly tighten it, the plastic is going to break off. But the good news is that it's easy to replace with better knobs. Look for any M8 knob (here on Thomann you can find Stageworx Hand Screw M8 or Manfrotto M8 knob). The cart is suitable for flat terrain. If there are bumps or cobblestone, you'll have to turn it into a hand truck and only use the big wheels. These are all small disadvantages, but the big advantage is that the cart is really compact and it fits between the front passenger seat and the glove compartment.

Quality is five stars, but unfortunately not perfectly practical.
The cart is a bit on the narrow side, That's not too bad, unless you use it to move an oversized heavy load (I tried today and that didn't work well). This and the fact it's not convenient as a two wheeler (no parts are conformable for a firm grip) kills a star.
The front wheels (larger sized) are non-inflatable, but the rubber has plastic feeling, no sponginess at all and tendency to slide on smooth surfaces under light or no load - another star has burned.

On the positive side: The locks for the folding sides are simple and sturdy.
It is not too heavy, quite compact when folded and quite well built. This bumps the stars up.

Assuming I have to buy another one, if weight and size are not critical, I would try Thomann's own brand XL sized cart despite I don't like the wired folding lock.
