Given the price of this thing, it's just great. I fitted a power plant in the designated space beneath using the rubber bands provided with the kit, and it sits really sturdy. It doesn't move around on the floor when you punch your pedals. I'm having some rather big pedals (like the Blackstar HT-Dual), but it still fits very well in the provided gigbag.
As I think someone mentioned already you would have appreciated id the Velcro tape would have been all the way out to the edges to maximise the space for pedals (now the left and right "frame" is without Velcro), but I solved that by adding some more on my own account. No big deal.
Great value for money!
