They took no responsibility when a large crack in the shell appeared. Both the contractor and Hawaiian blamed the other for the crack while the pool stood empty. For $30.00 I bought a fiberglass repair kit from a boat dealer and repaired the crack myself. Since I am not a qualified fiberglass repair person the same crack has appeared this year, 2007. I've called Hawaiian and sent a certified letter requesting that they send a "Qualified" fiberglass repairman to fix the crack properly. It's been over 3 weeks since they were contacted and I've had NO response from Hawaiian Pools. I'm not sure what the outcome will be but I would NEVER purchase a Hawaiian pool again because of their total lack of customer service when you need it. Oh, by the way, this is the 2nd Hawaiian shell in our yard as the first had to be replaced because of numerous blemishes and cracks. The theory is good regarding a fiberglass pool, just don't buy a Hawaiian Fiberglass Pool. Buyer beware !!!!!!!!!!
