I conducted some research on this website before buying my hot tub so I feel obligated to post a review. I purchased a Freeflow Sport RLX in February and so far, I am a satisfied customer. It was delivered at my home and I filled it up with my hose, plugged it in and within a day I had a hot tub! The Freeflow RLX does not have a lot of fancy features but it is a great hot tub for the money, in my opinion. I also looked at the Dreammaker X400 but decided the Freeflow looked better and had a heater for about the same price.
Thanks for great information resource.
