Is This the World's Worst Instrument? (Hohner Concertina) Review

My new channel: Milan Recording Studios Since making this video I have found comments saying sticky buttons are a problem, but have yet to find a reviewer talking about the problem.  So I thought I would buy a concertina, to see if it&possible to buy a small, affordable instrument to have some fun with. However, this particular one is incredibly poorly made and has a number of design flaws that make it impossible to make music with, or even just pleasant noises for that matter. I do not recommend anyone buys this instrument. I was disappointed.
