Make sure you have "3 in 1" oil nearby and oil the blades before and after each use. Use an old toothbrush to clean the blades while wet with oil and then wipe the excess oil and crud off with a paper towel. Store in a dry place away from bathroom humidity. I've found that the cheap ones just don't do the job and a while back, I decided to pony-up for a decent one. So, the reality is, cheap ones don't cut that well and even the best ones won't cut well if you don't keep them cleaned, oiled and rust-free.
