Excellent! Product came well packaged, fitment was to within 1/16th of an inch and quality was outstanding. Since installation we’ve incurred several Tennessee thunderstorms with wind gust in excess of 50 miles per hour. Our vinyl enclosures worked perfectly well. We would highly recommend PES systems to anyone concerned with rain, wind or temperature issues on an outdoor living space. Our neighbor ordered his enclosure from Brand-X and after seeing the quality difference, wished he had ordered from PES.
