A good month ago, I bought the "basic" Hottop. I didn't think the extra cost for more (electronics) was -at my stage of involvement- justified.
I've now roasted (only) 4 times since it was delivered to me, and each roast has been fabulous, a revelation. For those who wonder "why only 4 roasts in a month?" well, I still have some store-bought roasted beans in the freezer, which I'm using up "in between". Also, my consumption of coffee boils down to only 250 grams per week...
I admit my roasting is 100% manual (except for the electrical motor powering the rotation of the drum). I literally sit in front of the "bean window" and observe the machine doing its thing. Set to "manual eject" (power level 7), I sit through first crack and try to pick up 2nd crack to eject within the beginning of that, any case not beyond intended "city".
I like the basic simplicity of this machine. A rotating drum, a heat source, a filling orifice, a dumping orifice, and a cooling plate. Steel, almost no plastic. I've removed, after the 4th roast, the drum, so as to remove the chaff in the very back of the "drum chamber". Everything is "hardware". Easy to clean, stainless or chromed steel.
Some minor quirks: the removable glass window mounting plate allows water to infiltrate, so it should be removed for washing the glass. A detail.
Question: would all screws in this machine be "metric" or "imperial"? Given Taiwan I would think the latter, but maybe some one knows for sure?
