i would be to embarrassed to put my name to these ideas 
LOL!
I try to be nice to new start ups who are struggling to buy gear,.. but if I passed a guy using one of these I really would struggle not to laugh out loud at him.
Its not just the look of it though, a wheelie bin shape does not make a good trolley even if it is smaller. It'll be:
*hard to drag any real distance about because of the shape
*near impossible to get up & down steps with those little wheels
*top heavy because the pump box is on top
*not very stable on sloping ground
*prone to spillage when full
AND you'll look like a plonker!
