Clippers not cutting
The set of purple mini Wahl Bravura's are awesome clippers - we use them on toy poodles faces and feet. Also small dogs pads. Blade sharpened professionally, they just don't cut hair. Yes we oil them.

It is not unknown for a sharpen to be no good, anyone can turn out a bad sharpen. Look for correct blade assembly, check that there is sufficient pressure holding the blades together, check there is no missing stroke. Check the blade is secure and not wobbling. If the above are OK I would buy a new blade. You could also return the blade with the clipper for the sharpener to test for themselves.
Turn them on.
