It's usable to some extent, but it's a junk item. I apologize for the repeated listings. Since it's a junk item, please consider it for parts or for those who can repair it. I used it for about two months, and there were contact issues with loop5 and loop6, and they didn't respond when stepped on. It was fixed by turning the power off and on again. It still works now. However, I don't know what will happen in the future. Also, I once applied a 12v voltage to the leftmost 9v out. Also, I'm somewhat concerned about switching noise (about the same as a serial board). The appearance is in good condition. As it is an electronic device, I am not responsible for any future deterioration. I strive for smooth transactions, so thank you for your understanding. 【Please read before purchasing: Important Items】 1.
