I purchased the Thon Rack 2U Eco II 35 right before moving apartments, as my Fractal Axe-FX Ultra didn't have a proper rack case yet, and I wanted something cheap but protective for the ride (as well as maybe bringing the unit to a few gigs or rehearsal spaces in rare cases).
Pros: the construction of the case is pretty sturdy, and with the Ultra it leaves enough room in the back to keep the cables.
Cons: as the price suggests, however, the walls of the case are made from a relatively elastic material which may not fully protect against impacts.
So generally speaking it's a pretty good case, but I would not recommend this to a touring musician, only to someone who carefully wants to move their stuff once or twice a year.
