This is my Third spa and first from Summit Spas of Windsor. Summit was extremely easy to work with. The Caldera Salt Water spa is a huge improvement over my 2 chlorine spas. Much better for my skin with no residue, I don’t feel like I immediately need to shower after use with salt water. I’ve made multiple calls to summit for first-timer help on maintaining the spa. Summit took extra time to help me, being very patient. I highly recommend Summit Spas to everyone! The entire (ongoing) experience was very pleasant
