Andreas Volk 1 It’s very inconvenient to roast coffee beans with this product, because it is so small. You will have to roast your beans every other day, which is a lot of work and time. Also, it is difficult to roast the beans evenly even if you non-stop keep moving the roasting device. And although this is a simple device, I paid a lot of money. I only found out later that you can just use a regular frying pan for better results and with less work. I don’t recommend buying this device at all.
