I have one of these bamboo ukes that I got on sale, too. I actually purchased a soprano and a concert at the same time. I really like the soprano. Mine is fairly loud and bright without sounding thin. It looks pretty and my friends like it. It's sort of cool that it's made out of panda food. I think it's a bit silly to have a cutaway to access the higher frets that don't exist, but I don't regret the purchase. It needed a bit of set up, but what uke doesn't.
The concert was a complete dog, though. Fit and finish was not good, it had uneven frets, and it sounded kinda bad too. That one was quickly returned for a refund.
At $80 you can't go wrong and if you don't love it send it back.
Cheers,
Russ
