Wet test wet test wet test!!! try them all!! that's the only way to figure out which one you like, walmart and home depot and thermospas are all ones you cannot try so what I did was just take them out of my comparision shopping. I tried hot springs, bullfrog, caldera, and Coleman, and choose the coleman.
What you have to do is decide what your buying a hot tub for...like with me it was for some pain relief on my lower back so I was looking for a hot tub that had jets that hit my hips and lower back. Wet test all of them! soon you'll find your in spatopia with the rest of us!
