Dryer no longer heated

Unplugged appl. Removed back. Removed housing for heating element and proceeded to follow your informative video. Replaced burnt out unit with the new one & ZipZap we were in business within an hour probably less. The most time was spent on replacing the dryer vent which we found completely blocked with enough lint to blanket Rhode Island. Your fast delivery exact replacement part and perfect tutorial have not only saved us the cost of a new dryer but probably kept our house from burning down....we now will keep the vent clean clean clean. Thank you...Your devoted customers
