The LED lights in this tub are really nice and very bright. They have multiple settings and modes. We really like this feature. The other thing we like the most is the ozone system. I didn’t want to use chlorine or bromine so I opted to add the Ozo system which claims to remove most of the harsh chemicals from the water. Having owned hot tubs and pools in the past, I can attest to the fact that this ozone system works! We rarely have to add chlorine to the water. Only when we first fill it. Even if the water gets a little could after use, the hot tub actually cleans itself. Really really nice feature. We’ve grown tired of maintenance like this with our other pools and hot tubs. If you have the option of getting ozone in your hot tub, get it!
