Product review (3 stars): Heat Keeper kit
Works as described. As mentioned by other reviews, the so called "zip ties" DO NOT WORK. I have no idea how they are suppose to hold tension. Slapped some real zip ties on there and it's been holding up great. Screen isn't very fine and could use a better filter for the lint. I would recommend for the price if someone is trying to conserve some energy and recycle heat from the dryer back into your house.
