I bought one because:
1. I work with individuals with mental disabilities, and I play uke for them for music therapy, and a locking case is pretty much a must. Even though it's a tough uke, I don't want to think about what they'd do with it if they got ahold of it.
2. The same thing will go for when I reach my ultimate goal of teaching special education.
3. I like having the extra cavity for a tuner, capo, strap, other crap I carry around with it.
4. When I travel, which is frequent, I don't have to worry about it.
5. It protects all the stickers and crap (and Jake's signature) on it.
6. I like it.
I should have included a "Yes, if it's a solid top" option.
