This thing actually sounds godawful, but that's because it's a banjo ukulele, and they're SUPPOSED to sound godawful! That's what makes it so fun and useful!
Think of this instrument as you think of spices in your kitchen. You would never eat spices alone because they taste real bad on their own, but they can really improve good food and make it more interesting. Banjo ukuleles are like that!
I've never seen another banjo ukulele IRL, so I can't say if this one is any better or worse than usual for the breed, but it seems well built to me. One reviewer said the tuners are bad and needs replacing, so I ordered a set. But the tuners on the instrument are actually just fine, so I didn't bother changing them.
