I spent a few hours yesterday cleaning out my gutters... AGAIN. I have to do it every 2-3 months or else my downspouts clog. I can usually fill a 100 gallon recycle bin with the sludge (I live next to a couple acres of trees).

This part of home ownership sucks.

I know there are several products on the market that cover/screen/prevent crap from filling up their gutters. Anyone have these, and most importantly do they *work* well? I'm reluctant to outfit my entire house with the things if I'm just going to be tearing them off in a few months, plus they aren't cheap.
