I will try to be as fair as humanly possible here: even with apparenlty identical features, the quality here is not comparable to my other rack cases (mainly old SKB, some Gators and plastic Anvils that had been in my rig for ages) BUT, again in full fairness, those cost more than double the price. At this price point, this rack is unbeatable.
Stability and perception of quality is also affected as the case becomes larger. I had the chance to check the smaller Thomann 2U and the impression, obviously, was better. Mine is one of the largest (6U) so stability and structure suffers from thinner materials (again in comparison with cases costing much much more). I guess that if heavy travelling is not on your immediate schedule, this case is perfect. If you are about to kick off your world tour next week, you might consider a more challenging investment.
Having all that said, I am again grateful that Thomann is offering a cheaper alternative for all of us stucked in our home studios. So far, did get the job done flawlessly.
