The Tombo Ultimo Diatonic is a nice little harp, but it isn't particularly unique among diatonic harps. Like many of them, it has 10 holes and a plastic comb. It also has shiny covers, like many other harmonicas. One unique thing about it is that it has rounded edges, making it look more like an oval than a rectangle. It's got good playability and a decent sound. However, other models, such as the Hohner Special 20, tend to have louder and crisper tones. It's a nice harp for playing a few Jazz or Fusion tunes, or for playing simple melodies.
Durable and sturdy
Many other diatonics with only slightly higher prices have better sound quality
