We have enjoyed our pool from Blue World Pools.Not much upkeep.
We have had Blue World call us as well just wo make sure we are happy with our pool and make sure everything is okay. The customer service is good. I love the extras that came with our pool like the ladder that locks upright keeps my kids safe. My installer was very good and knew everything we wanted to know about the pool.
Also the vacumm that comes with the pool is wonderful just put it together and let it do its thing.We are very pleased with Blue World Pools.
