I do not have an expensive CBA to compare it to but I do have button accordion experience. This is a student instrument at a price point that can not be beat. If you're in the US like me where this instrument is not common, it's the cheapest you can buy a playable CBA (new or used), includes straps and a gig bag, and comes with robust warranty. I can attest that even in US the warranty works as I had to invoke it when my first instrument arrived unplayably damaged during shipping. The return process was extremely slow and an incredible hassle, but I was ultimately able to get a refund though I believe I ate part of my own return shipping. The second instrument I was sent is nice and playable. It's student quality but perfectly good for learning and making music on, and I'm impressed...
