Used once. I stored it at home for about a year, but I'm selling it because I don't use it. Operation confirmed. It works without any problems. It's in good condition, but please refrain from purchasing if you are sensitive to used items. Please take a close look at the images before purchasing. There is no outer box or instruction manual, but all other accessories are included, so you can use it immediately. You can find the manual by searching the internet. I will disinfect it, wrap it in cushioning material, and pack it in a suitably sized cardboard box for shipping. Thank you.
