Product review (4 stars): Dryer belt replacement
Used to help me fix my dryer.  Vacuumed out the inside of the dryer, replaced the dryer belt and pulley and was amazed when I closed everything back up and turned it on to find my dryer work again.  Not sure how much longer it will last but it's been quite refreshing to have the dryer operate in a much more quiet manner now and actually dry the clothes quicker and more effectively.
