I've only used this a few times since purchasing it. I'm selling it because I've become busy with work and can no longer find time to play. This product has silent specifications, and as shown in photo 9 (the back of the outer box), it uses dedicated silent buttons and a silent lever. I feel the silence is quite high. * I have not made any modifications after purchase. Also, as shown in photo 4, the main unit can be easily opened and closed. If you ever want to replace the lever or buttons with your preferred ones, it's easier than other models, and the ease of customization and maintenance is also a魅力 of this model. If you look at the official website, there are instructions on how to replace the top panel illustration, making it a product that you can use with affection for a long time. Regarding operation, I have confirmed that it works on a PC, and I was able to use it without any problems. I do not own a PS4 or PS5, so I have not confirmed operation on a PS. The outer box, instruction manual, and everything that came with the purchase are all included. Please check the photos along with the condition of the product. I am a non-smoker and do not own any pets. Thank you.
