I have the Luna solid koa concert, and it is a nice little uke, comparable to Kala and other good quality budget ukes. Don't expect it to replace your K-brand, it's not at that level; but if you go in with reasonable expectations, it's a nice uke at a fair price. I have not had issues with intonation or setup, but any factory uke will usually need some level of setup before it gets into your hands.
