I used this instrument in every possible way, and played it for the production of different kinds of music. It just sounds good.
Pros & Cons
The sound and material quality of this instruments is very good for its price. The release of the sound at each hit on the tines is long and gives a calming and harmonious sensations. The screws of the z-bracket are easy to adjust for fine tuning. The box hole is different from traditional kalimbas, but it allows you to create a wah-wah effect that sounds pretty good. The long decay of the sound allows the player to make long and precise wah-wah sounds. Put a reverb on it and you are good to go. Therefore, the box hole adds more possibilities to the instrument than traditional kalimbas.
The kalimba fits good in an adults hands. The only remark I have for this one is that the outer black part of the instrument is too polished, and can cause the instrument to slip. Most of the time the slipping is prevented because of the moistre on or hands.
Price
At first 49euro might sound too much, but it's worth every penny.
