It doesn't matter how big or small is your setup, this trolley can take it.
Mine consists of:
2x10" satellites
1 fairly large and heavy sub
1 76 key keyboard
1 cable case
1 mixer case
1 speaker stands case
1 microphone stands case
1 keyboard stand
...and I take all of that in that trolley in one go. How awesome is that, eh?
It folds and extends depending on your needs, and can carry a lot of weight.
Don't hurt your arms and back, and get yourself one of those, and thank me later.
Pros:
Very sturdy and easy to setup.
Can carry up to 225kg !!!
Big wheels.
Relative to how much load it takes, it is very compact and light on it's own.
Cons:
It rattles a bit when passing over uneven surfaces.
Resume:
It's one of those things that makes your life much easy. I can't see myself without it anymore.
