Absolutely brilliant design and I think this product will soon become the only goggles to buy. First scan needed some tweaking but Caylan and team were determined to get it right and the service is immaculate. They immediately sent me a new set of goggles at no additional cost. I really liked the concept and they were very comfy. The fit is comfortable, they sit on my face different than any former goggles . The vision is clear, and the peripheral vision is better than any other goggle I've worn. Now that I have used the Magic5 goggles for a month I will never go back. What a difference, fit perfectly, and no puffy eyes after a long swim. Thank you.
