The two scenarios I believe this instrument should be purchased are: if you aren't sure that you'll like playing the concertina and want to try it out, or if you just want something to squeeze and goof around with your friends

This concertina performs well, and has a good tone

I bought this, played it for a week and decided I liked playing the concertina enough to upgrade to a brand a few hundred dollars more expensive

So if you're not sure about if you'll enjoy it or not, purchase this, but know that you'll likely be upgrading to a decently more expensive beginner concertina in the very near future.
