The Hering Super 20, like many other Hering models, has brass reeds and cover plates. It also has a stainless steel and plastic body. However, unlike many other Hering models, the 0.90 mm reeds don't offer as much consistency as one might like. Some people have complained that their Hering Super 20s need some reed adjustments or replacements right out of the box. So, while the price is reasonable, it isn't without its risks. Nevertheless, replacement reeds are available, and this model comes in 12 different keys. So, it might be a good harmonica for beginners, but serious harp players may want to opt for a more reliable model.
