Product review (4 stars): Ewwwwwwwww...that's been stuck in my vent??
Easy to follow instructions... Hubby managed to clean out the dryer vent within a few hours.  Unfortunately, our vent ends outside on our rooftop so we couldn't do it from the other end... but still felt that it was worth the money to take out all the lint from one end.

I just wished they included more of the rods instead of having to order an extender (that's why I left off 1 star).

I would highly recommend this.
