I use it to transport my Laney 12r.
Body: What I really miss, is the handles to be larger, so I can carry it comfortably. That would increase the overall size of it, but, you would get a nicer carrying experience and your back and arms will be more relaxed. Probably for even taller guys then me (I'm around 183 cm), it will be even harder to carry it around, cause you have to bend a bit your body.
Wheels - they can be larger and softer! I think my amps gets a lot of bad hits and it will break up at one point!
It does the job, but not as it can, once it is approved. Size is super nice and compact, and decent built!
