Experience with the no dev fee kawpow

Just wondering what everyone's experience with this miner is like. I moved from trex where I was recently getting 27.7 reported by trex (though actual payout the last few days was around 30 mhs). I'm getting around 26 mhs reported by the miner and just wondering if others have had a different OC for this miner.

Also I couldn't figure out how to get the latest 1.2.4 version working (there was not bat file to edit) when I downloaded from github so I just downloaded the one from ravenminer (1.2.3) so hopefully that's not an issue.

Also anyone know if I can make this show my power draw or efficiency numbers?
