Product review (4 stars): a little big, but it does the job
Up until I got this dryer vent brush, I was using a toothbrush taped to the end of a chopstick to clean my dryer vent (yes, I know- it never occurred to me that a dryer vent brush was out there...)

I love having this brush- it's made my life so much easier. The only thing I *don't* like is how big the brush part is. It's almost too big to get into all the crevices in the lint trap, and because it's so long, it's hard to maneuver. But overall, it does a fantastic job, is very flexible, and really helps to push the lint out and away from the dryer.
