In my opinion 0.5% devfee version from Rwteam is best solution - no need to run as administrator, no external drivers/apps. According to their readme, 63% of devfee is still going to developer and other 37% to rwteam, but miners pay only half of devfee which is the main point of all such "devfee removers/reducers".  Lately i switched to their Phoenixminer 0.5% version because people say that phoenix is faster than claymore, wanna test it.
