Has anyone had any luck with the Lint Lizard? I saw it on a commercial and thought it looked great. For those that haven't seen it, you connect a plastic hose to your vacuum and it gets the excess lint out of your dryer. I am always having problems with my dryer vent. It always get clogged, even though I clean the lint filter every time I use the dryer. I would love some feedback on this product to see if it is worth sending for.
