You guys have already done that for me, so thank you for that! My last order of 1000 Avalon 741s came with 20 spares, of which we have only had to use 13 in the last 9 months.

Canaan has no equal in this industry as far as the reliability of the units go. The issue for me has always been efficiency and price. While I dont mind paying for quality, its hard to take a hit on the efficiency side when you are talking thousands of units like I work with.

In my experience, the reliability has not made up for the power usage. It looks like with the 8 series you guys are on track to be at least competitive in that regard and I cant wait to get my test 841 and put it through the gauntlet.
