Purchased in 2020. I haven't used it that often, but the main unit's push buttons are a little hard to press and release. ※ See photo 2 Therefore, using the remote control is smoother. All functions work normally. The remote control has some scratches and scuffs. I will include the batteries when I ship it. This is being sold as a junk item, so please consider this only if you understand. If you have any questions, please feel free to comment. Also, I will offer a small discount for those who wish to purchase.
