The built quality of the case is great, but there are no wheels (like on the case for the Arturia Matrix Brute) and it makes it extremely heavy and difficult to transport. Also an extra handle on both sides would have been nice to make it possible to be carried by two persons. I'm so glad I bought this hard case!
... I've started using my Arturia Polybrute for live gigs, because, well because it's one of the best synths around. The soft cases are useless and it's very easy to damage your synth with them. This however is a game changer. I'm also surprised at the price, which is very reasonable, and I have to say both the interior and exterior build quality is exceptional.
The only real gripe i have is that as the PB is pretty heavy already, adding the weight of this case to it means you need a bit of upper body strength to carry it, but that's a small price to pay for ensuring my synth doesn't get dented. Thon cases always work extremely well and this is no exception.
The Polybrute fits perfectly and is well-protected from bumps, scrapes, and impacts. Very high quality hardware and the case is not too heavy, so it works great for my needs.
