As a new HotTub owner of 1 month naturally I had lots of questions and concerns as to whether or not it was working properly. From the start the salesman Keith at Best Hot tubs in Farmingdale NY was extremely helpful from guiding us on how to install the filters to proper chemical usage. Then when I still had questions and concerns the owner of Best Hot Tubs gave me his personel cell number stating call me anytime and I did he always answered and assisted me. Finally when I was experincing a very minor valve issue they sent there technican Matt who was extremely patient and knowledgeable, He quickly repaired the issue and then proceeded to teach me how to properly operate my Hot Tub. The team at Best Hot Tub is extremely Knowledgeable and Professional. I highly recommend Best Hot Tub you wont be sorry you went with them.
