Query: Poor design

I purchased this trimmer in 2006, and ended up using a cheapo trimmer that I picked up at Marshall's much more. The Panasonic trimmer, sadly, never worked as intended. The cutting blade part would get stuck in the cap assembly, and only much careful adjusting could cause it to spin. When it did spin, it did not do so properly - the blades would get stuck on the head assy and it would stop spinning. This made for a very annoying and at times painful experience. I'm not giving up on Panasonic and after my el cheapo groomer died, I am getting a Vortex trimmer which seems to be rated higher than this one.
