Small Folding Hand Truck Dolly with 2 Wheels, Lightweight Aluminum Foldable Luggage Cart into Backpack, Collapsible Carts Portable Dolly for Airport Travel Moving

I liked that it could be fitted into my rucksack for checking on to aircraft but easier than a suitcase when changing modes of transport.

A bit hard to manage, bought it for my bag I take on the plane in the end couldn’t use it kept falling off

It works, although a bit flimsy…

The most annoying thing about this, so far, is that the adjustable height handle only locks in a few of the possible positions.If you want to use it at its 2nd from top height then the handle either won't lock or won't stay locked for long which is no good.I tried 2 in case one was defective but both have this issue. The handle and its locking mechanism don't appear to be that robust either but you get what you pay for. Not that a low price is any excuse for lack of fitness for purpose.
