Purchased new in 2023 and used about once a month. I'm selling it because I've bought a new roaster that allows me to manage data logs on my PC. It runs on a Japanese-specification two-prong 100V outlet. Currently, I can't find any sites to purchase it online, making it a rare item. I have thoroughly cleaned it as much as possible. As shown in the photos. However, the stainless steel drum (the cylindrical part where the coffee beans go) was soaked in baking soda four times, and I was able to remove about 90% of the burnt-on stains, but not completely. There are no issues with its use, but please be aware of this. (The charring will inevitably accumulate again during use, so I don't think it's something to worry about too much.) Here are the personal pros of this roaster: 1. Quiet operation (no fan noise like hot air roasters, just the sound of the drum rotating) 2. Equipped with a flame arrester, so smoke doesn't leak out much 3. Can roast up to 400g at a time (more than enough for home use)
