HI - They both seem fine - just as 'light' to the touch for the extra fine focus, and ok for the normal wheel too - both seem well made etc. - The WO was the right size to fit the electric focusser I had wheras the Bintel 'axle' was thicker - otherwise Id just keep the Bintel. (though Im sure I could make/get something to make the focusser fit to the bintel axle)
