Hello and peace be upon you, mercy of Allah and his blessings. I have a recorder that is clean and opened for the first time from its agency. It works quite well and all its functions are good, but the problem is with the right-side volume knob which increases and decreases if I adjust it; however, all other aspects remain fine. No comments or anything else, and this issue is known in most recorders, so if it gets cleaned it goes back to normal. Hello and peace be upon you. If there is something not mentioned by me, your money will be returned. There is a slight crack on the inner corner which doesn't affect it, but just to clear my responsibility I mentioned and photographed it. - Bluetooth works - USB works - AUX works - CD slot works ---------------------- Everything in it is working perfectly.
