Let me start with saying that Thomann's service and handling was flawless and I got my order in a perfect condition.
As for the FCB1010 itself - make sure you know what you're getting into before you get it. It is a very popular product that has huge dedicated forums with thousands of members, talking about it, fixing, optimizing, modding etc.
The build quality is exceptional. Its heavy duty (literally, it has its weight...) and as such feels solid and appropriate for handling a live performance on stage as well as anything you throw at it at home.
The biggest con is in its lack of a usb interface, meaning you have to use a midi-to-usb cable if you need that functionality, which was my main use case. Although it is possible to use 3rd party software to edit, upload and download configurations to the FCB1010, the 'official' configuration method is done within the device itself, and it takes time to figure out, especially if you've never worked with midi codes before. For me the best way to learn was watching an hour long youtube video explaining and demoing every setting, which just emphasizes how feature rich this thing is :)
