Purchased new in 2025 and used only a few times at home, smoke-free, no pets, and never taken outside. Includes the main unit, box, and MIDI cable. The unit has been used for a short period, and as far as I can see, there are no noticeable scratches or stains, but there may be minor scratches that occur with normal use. There were no malfunctions during use. This is a unique instrument, so please check the online manual for usage instructions beforehand. Takazudo Modular's explanation is helpful. https://takazudomodular.com/notes/2023-12-06-wingie2-intro/ You can change the sound to a unique tone by resonating percussion sounds. Applying a lot of delay creates a feedback loop-like effect, and I was able to create not only beautiful sounds but also rough sounds. Personally, I found the built-in microphone difficult to use, but I enjoyed making bass sounds and distorted noise by blowing into it.
