I ordered this case because I wanted a solid storage and transport solution for my Mopho X4. This is exactly what I wanted. It is very well built, and the synth fits perfectly. Very solid construction. The only complaint would be as others have noted, there is no room in the case for the power supply. Other than that, it is perfect.
Thomann was amazing in its customer support. The first case they sent was stolen in transit, most likely here in the US. The postal service on this end did nothing, offered nothing and was less than helpful. Thomann on the other hand, initiated the paperwork and sent another case. Because the first had been stolen, my credit card company kept trying to put a chargeback on this purchase despite my instructions not to do so. Through it all Thomann was professional, its customer service representatives responsive, and as a result, I have the highest respect for this company. Many thanks!
