i use the same 'suspect' one and works just fine. it has however started to warp.
Panda, Tell us more about your approach? compounds...
One thing you can give and still keep...is your word.
I just lay it flat horizontally on prep table and use moderate pressure, unloaded. Angle of approach is that of higher than the edge, I'd guess 5-10deg more. Starting at the tip and sliding on a bias ending with heel.
Panda, Thanks. I loaded mine with 1u Diamond spray. Tried raising the blade above sharpening angle but it just rolled/polished the edge. Given the you've had success, probably means my technique needs work. I'll give it another try.

Doubt it, you probably got a p.o.s. One.. Quality control issues maybe
