As a trumpet player, I wanted to make it easier to transport my Yahama trumpet, protec mute bag (6 mutes), and music stand bag (with music stand, foot pedal, cushion and other sundry items) Whilst all three bags have straps, they get heavy quickly and it's awkward to keep them all in place for anything longer than a short distance. I tried using this trolly, to pile up everything, so that I could release the pressure on my body. I have been able to stack all three bags on the trolley, but it's not perfect. I had to strap them down tightly with bungy cords, but even then if travelling a long distance to my car (can be 1/4 of a mile depending) I found that the items might work loose, meaning that I'd have to reset things. It does work, and I'm sure that with the ipaq cases it would probably work alot better.
