In terms of space, I fit something like 3 MXR type pedals, a wah, a power source, a pog and my amp switcher ... So sometimes you lack a little bit of space, but this wasn't the fault of the company and it makes me less distracted by pedals, so that can be a good thing.
The bag is really strong and protect your pedals really well, but I wouldn't "tour" intensively with it !
That's why I'm talking of a semi-pro use, that's a massive upgrade from the DIY cardboard box with a wood board. It has lasted for a long time with me and travelled a lot, and hasn't any trace of use of it. And it is not handled like a baby ! So this is a really really great buy for me. And is easy to carry with me, even in the bus if you have some space under your legs.
