My first goggles were leaking, but after contacting support and providing some additional photos, I received a second pair very quickly. It still took me a couple of weeks to find the good position of the goggles. While during the first trainings, the goggles were leaking until after several adjustments of position, I had the first openwater swimming event with them today, and they had the perfect fit from the beginning. The absence of pain/pressure, the very big field of vision and the fact that they don't fog up at all make these goggles my absolute favorite. Support was very friendly, reactive and helpful.
