Query: Best Dryer Vent

We installed one of these vents shortly after we bought our home 10 years ago - and it's worked perfectly all these years. It stopped the cold drafts coming back down the dryer vent and has never jammed in venting out the heated dryer air. And no insects or small animals have crept up the vent, something several of our friends had to deal with recently. Worth the cost!***UPDATE***Now at 13-1/2 years after installation, this thing is unstoppable. It will probably outlast the dryer, frankly.
