Easy to install, fit perfectly. I've put 250 sq.ft. through it without incident. Two reasons for four stars: #1 I paid extra for two day FedEx delivery to be on a Thurs. Tracking said delivery on Thurs. Then it went dark until Sat AM and said Monday delivery. Package showed up Sat. night without plastic cover just before a big rainstorm. 2Sand should get a rebate from FedEx. #2 Belt would be better @16.25 inches as per manufacturer's specs.
