I too can confirm - I have 4 Furys (Blizzards) pointed as CS, each running 1.33 MH/s and over 3 days my reject shares are between 24-26%..... I'm not sure the reject percentage is accurate on CS, or if its a function of the Furys.

I also average about 2% reject on CleverMining.... Again, this is just what the stats show, so I'm not really sure where the problems are coming from.... Its also worth pointing out that despite rejects @ 2% CM and 24% CS, I do seem to be generating about the same amount of BTC per Mh per Day on CoinSolver and Clevermining.

Edit: The % I mention above are poolside. zenminer AND minera (furys/blizzard and gridseeds) show different reject percentages. 

I recently bought a GAW miners fury asic. It can do about 1.3 MH/s. every time I point it at coinsolver my rejected shares hit 25% to 30%. Other mining sites like clevermining.com I only get about 2%. The Fury is a Clone of the Zeusminer blizzard. Has 6 chips just like the blizzard. What difficulty level should I put it at? I’ve tried a few. None of them change the reject level much.
