If a miner gives you +10% hash and has a 2% dev fee, you're netting +8%. It's not too high if it delivers performance. People will complain about anything.
Anyone have some 24hr comparisons on pool (not local), such as yiimp? Easiest way to tell what sort of hashrate this is putting out.
Yah, I always think its ridiculous that some of these people will bitch and moan about a 2% fee, and without even trying the miner. It takes 10 minutes to download a miner and copy your bat file to test its performance. If its worse then move on to something else. People have honestly been spoiled by tpruvot and KlausT.
I will say though I'm not a fan of closed sourced miners from non-reputable sources. With all of the AV false warnings it makes it difficult to run something like this.
