I was successfully cutting my son's hair when he started to complain that the clippers were pulling his hair. I noticed they weren't triming it anymore either. This is a remington hair clipper-electric- i'm sorry I don't have the make/model but I just purchased it about 3 months ago and have only used it about 5 times.
Mine doesn't seem to work very well. It's the model that's cordless. It's so weak that it can barely take out a few short strands of hair at a time, and the crazy part is that I just bought it two weeks ago. It says it's titanium coated clipper and doesn't require oil to lubricate it.

Sorry if this is a bit obvious, but did you try oiling the blades?
These things often come with a small bottle of the light oil they use. Try a little & run the clippers to see if they seem better before trying them on your son again.
