Query: Worst Beard Trimmer I Have Ever Owned

I have owned many beard trimmers. This is the worst of all. It can not make single pass without PULLING and SNAGGING your beard hair - and that is both very annoying and painful. After several attempts to use this on different days - making sure it was full charged - the results were always the same and I simply want to smash it into little bits for all that beard plucking pain it has caused me... Maybe the one I was shipped never had its blades sharpened or something, but it mainly pulls - it does not cut worth anything. I'd love to demand my money back but I can't figure out how.
