Nightmare from start to finish. Contractor they used was unprofessional and unskilled. Installed liner without insulation that was paid for (which was sitting on the deck ("I'm glad you said something"). puncture holes put in new liner, ground wire sloppily roued along pool side, creases in bottom, broken return that installer tried to cover up with putty before we realized it was leaking like mad. Came back and "fixed". Let me know if you would like additonal details - have all kinds of unanswered correspondence, including a communication from the NY Better Business Bureau indicating they never received a response either. Rating is an F there as well. Several calls, e-mails, letters to company to either replace or remediate - nothing of substance returned. Left one message saying he was sending liner manufacturer represenative out that day (with no one home and deck locked), and never heard back from Frank. Have heard similar experiences - do yourself a favor and run!
