Product review (5 stars): Stop Air Drafts & Rodent Protector
Excellent Vent.
Not Only Is The A Rodent protector from squirrels or rats,
It's An Excellent Protector Against The Cold Or Hot Weather.
With The Contractors Grade Vent Normally Installed On Houses > It Let's A Lot Of Cold Air In Through The Dryer.
That Why I Bought This Heartland 21000 Dryer Vent,
To Try To Stop So Much Cold Into The House.
I am so excited to say this is by Far the Best investment I've made on my house in a long time.
The Laundry Room Is Staying Warm In this cold weather > NO MORE AIR DRAFTS.
Best fifty dollars I've spent.
Will Save On My Heating Bill.
Wish I Had It 20 Years Ago.
