I like mine, only used it for a few hundred miles so far, second gear (bigger ring) does feel a little bit draggy but if I need it I am already ploughing at a decent pace or going downhill and you don’t notice it so much.
Surprising benefit is that it doesn’t rotate the chain wheel when pedalling backwards, therefore when changing feet for cornering berms and such like, your chain never gets hucked up on the block or on the chain guard.
You also get better ground clearance, no bashed rings.
