They are the biggest crooks and scammers I know
The liner will only last slightly longer than they will warrent it.After the 90 days are up you will probably have grass growing through your liner.
I also have a sink hole under my pool now from where they left a backhoe in my yard in the same spot for more than a month. And thats after being canceled on the installation for over 6 months. I bought the pool and didn't even get to use it at all that year. Well in fact I havent been in it at all due to problems with it and missing parts and so forth.
I even have a show pool and blue world pools doesn't even want people seeing their own pool because its sooo messed up.
I do not recommend getting a pool from them, however I do recommend blue haven pools out of san antonio tx.They are great pool and people!!!
