I love this spa for several reasons but the main reason is the ability to switch around the jet packs. Certain packs feel better in different sitting scenarios. There has been a couple minor issues that knocked one star off. One of the less aggressive jet packs has small holes for a soft effect, well those small holes create back pressure on the system and the little plastic inserts on this panel like to come out when the pump is on stage 2. I’ll be trading out that pack shortly. The other odd thing is occasionally pump 2 doesn’t come on, and I have to reset the system…then its good to go. I still need to report this to Bullfrog and I’m sure they will take care of the issue! Amazing foot massage while in the lounger but awkward to get foot massage from any other seat. I wish the center of the spa was formed in a way that its easier to hold your self back in the seat when sitting in a high output jet scenario. I do love the spa, and look forward to 10+ years of use before I go for a new one.
