I have never had a Kalimba before and I love it very much!
The build is good and I love the sound (but I am no expert on this, since it is my first time owning such an instrument). It really is a soothing instrument to play, but it needs a little time to practice.
It comes with a hard case, which is perfect for carrying around, a tuning hammer, and 2 rubber "thingies" to put on your fingers (still need to figure out how to use those).
It has a sound hole on the front and two smaller ones in the back, so I still need to learn how to utilize those.
Overall, very satisfied with my purchase.
