Can't hear the phone ringing 8 ft. away Unpredictable Undependable Not backed by manufacturer
Detailed Commentary
The first one they sent me caught fire. The second one is very unpredictable over or under roasting. The chaff container clogs with higher chaff coffees. Works best on decafs. Obviously you can't stop the roast in mid stream to empty the chaff therefore it means loosening the top so the air begins to circulate the coffee again. Meanwhile of course the bottom beans are scorching. Once the chaff blows all over the kitchen the roast continues with half the beans over or underroasted. It's unpredictability in roast temps and performance I was told the fault of our electric company. The purchase of a voltage regulator for the outlet at $150 will make it operate perfectly. If I wanted to blow over $300 on coffee roasting I would have bought an Alpinerost. I personally think a product should function under normal and expected conditions not ideal conditions. The storefront at Amazon is not interested in taking it back. So far it's burned half a pound of Kona among others. Buyer beware!
