I just bought this in April out of pure ignorance. I do not play wind instruments. I blew through it once and rolled my fingers on the keys thinking I'd hit random notes, but it only makes noise if you actually provide it with correct fingerings. There's fingering charts in the manual and I'm sure I could figure it out, but I'd way rather get the Leviasynth as this was an impulse purchase because the Leviasynth was out of stock. I already have an Osmose, which is more natural to play for me. I couldn't return it because I opened it. I cleaned and dried it immediately after trying it out, as per the recommendations. It's practically new. Comes with 2 sets of batteries and a charger that were purchased separately. Please, do not purchase this unless you know at least one of the fingering layouts and you are 100% positive you will keep it. Shipping Fedex Ground with signature. No POs. Thanks for looking.
