So I guess you’ve never played an accordion, Ted? Or an organ, or a Wurlitzer, or a keytar, or a Melodica, etc., etc.?

Standard piano sized keys don’t denote whether a product is a failure or not. Just an inability to adjust. B3 keys aren’t the same as piano keys. Is that a failed product?

It was a failed product FOR YOU. For those able to adjust, it seems quite the bargain.
