IMHO this doesn't even start qualifying as 'shady' as per Bitmain standards. They're selling units advertised at 10KSol/s - which can be overclocked by a minimum of 45% and a maximum of 60%. Period. 14.5 KSol/s is a great overclock over specs - whichever way you look at it. My batch 1 only achieves 15.5 KSol/s vs. the 16.5 - 17 KSol/s others are getting - there's some variation in batch 1 as well. Also, I've not heard of any Batch 2 machines which are getting less than 14.5 KSol/s.

"Shady practises" would include some of the following:

• Selling the first batch at $1999 and then dropping them down to $1500 and $850 within a month's time.
• Issuing coupons to people who paid full price for it - that's like saying - come on suckers - buy more from us if you want to make up for the drop in price.
• Advertising as "limited to one unit per customer" and then changing that to 50 units per customer in a weeks time, and then making it unlimited after that.
• Rebranding and releasing old models as new with some miniscule adjustments to dump old stock. S9, S9i, S9j - all basically the same machines. L3+, L3++ - same story.

And the list could go on and on.
