The website was not clear on measurements for an item (length? Diameter? Circumference?) so we ordered the wrong size. We're first told we could exchange, but didn't get e mail directions. Then told can't return items under $25. Been waiting for the supervisor to call me back. I've been on hold for about 2 hours over 4 phone calls trying to get through. Be forewarned... And the promised call from a supervisor has not come in over 48 hrs. Check out Leslie's Pool supply - cheaper and better customer service!
