Operation confirmed. I used it for several months, but I am selling it because I no longer need it. The AC adapter in the fourth image is included. There is a small paint chip on the back, but overall it is in good condition. There is no noise, and there are no problems with performance. I will carefully pack and ship it to prevent damage from water or impact.
