Home coffee roaster with a 550g capacity, quiet design, and APP operation. - Model Name: R2 - Maximum Capacity: 550g - Operation: APP operation - Design: Quiet design Purchased in July 2024. Includes all accessories and original box. Stored at home. Operation confirmed. This is a very easy-to-use roaster, but I am selling it because I need a larger one. I have roasted coffee about once a week, and have performed simple cleaning after each roast, as well as regular internal cleaning as notified by the app. There are some scratches, stains, and signs of aging from use, but it is still fully functional and can be used without any problems. I have cleaned and maintained it carefully, but please check the photos. Thank you. Thank you for looking.
