That is what I expected when I bought the "GECKO Kalimba 17 Keys Thumb Piano with Waterproof Protective Box, Tune Hammer and Study Instruction, Portable Mbira Sanza Finger Piano, Meditation Sound, Gift for Kids Adult Beginners Professional" from Amazon. After all, it comes with a 365 days warranty and 180 days unconditional return guarantee - too good to be true usually means it's a lie! But no... It turns out that the product actually works as advertised. While playing this instrument was still not terribly easy (despite their study guidance QR code), at least there are no hidden surprises like bad sound quality or rapid degradation of materials (handmade high-quality mahogany).
As disappointing as it was to not find any conspiracy theories while shopping on Amazon this time around, at least this product provides decent protection from shocks and moisture. Goo dsound quality in addition- unless your fingers don't cooperate well enough to make your own music that is otherwise considered 'wonderful'.
In conclusion - yes GECKO Kalimba 17 Keys Thumb Piano lives up its promises.. but you won't find any conspiracies here!
