I was sceptical of this hot tub, but it has turned out to be a pleasant suprise! For starters, the customer service is amazing. My outer liner got lost in the mail and customer service sent a replacement liner immediately. They are so good, they actually sent 3 liners in different colors to allow me my choice! The hot tub was super easy to assemble and in 24 hours, the water had reached 104 degrees. The spa itself heats up really quickly and the bubbles are more powerful than I thought they would be even though they come from along the bottom perimeter. With the jets running, there is temperature loss and the heater can't keep up. We are at high altitude where our winters are no joke. I am anxious to see how this hot tub performs in the colder weather. This is a great hot tub for the price, filling the massive gap between inflatable tubs and the $10k solid tubs.
