It's not a toy! Robust design. Also the mini keys are ok (melodicas also have mini keys). However, don't expect a good sound through the internal mini speakers. But when connected to the real amp and speakers, it's another story. Perfect. You have to adjust your normal playing if using only 3 octaves that are usually not enough for two hand playing. But you have midi so it can be connected to a midi controller. It works flawlessly, tested on 61 keys Roland keyboard. Unfortunately, the drawbars don't have 8 steps as normal, there are 7 if i remember right, so you cannot really set for example 00 6845 433. Selecting percussion on H sound can be frustrating if you don't read the manual-it has some speciality considering 1' drawbar and response of the keys. Again, read the manual!!! The YC is practical for traveling and if you're lazy you can sit on the sofa, have some Youtube instructional video or sheet music on the side, put the YC on your knees and practice along. Better than watching reality shows :)!
