I really like it. It's very reliable. Like all these canaan home products, it has had a nice price drop. I bought mine around 4 months ago at $399 including shipping. Now I see a $299 price. I think if I look to go bigger, I might go for the Q instead of the heat bit. They both have dropped a little in price, and I like the Q's hash rate. I would use it in the winter for a basement room that is not well heated.
