As a keyboards player, I have a fair bit of stuff to move around and was always running back and forth between venue and car.
I can now fit everything on this trolley and roll the whole lot in one go, and the trolley folds flat and also fits in the car.
It's solidly made, adjustable in length and mostly easy to roll around. The skeletal platform is the only real down-side, but I made up a plywood platform to drop on. On rough surfaces, things do tend to drift sideways a bit, but some rope or shock-cord stops that. I'm happy with that as I can put it at whatever height I like.
This item is a serious piece of gear for any busy wedding/function band. It's a must have. It has cut our loading time for gigs by half if not more. It takes the weight of the powered bass bins and powered tops in one trip. We've piled amps and monitors on to it without any problems. It really saves your back as there's much less lifting involved. I would highly recommend this loading truck to any busy band.
