Once we got past the software issue (app downloaded fine, just needed to be updated), these are terrific goggles - they work like a charm. They are REALLY well made, with great suction, and the easy-to-adjust straps are very comfortable and secure. At first, it seemed that the device would get in the way, but the general visibility is great, and there is surprisingly little impact to peripheral vision. The goggles fogged up in the first 400 yards during first use, but a couple of adjustments later, no fogging since, and the last swim was 2 miles. No leakage at all. The software output, compared to watch data, is definitely more precise. The data featured in the tracking is spot on and far more detailed than what was captured in the watch app. Each set is recorded perfectly, as it recognizes when the swimmer is resting. The running clock, splits, lap count (even within each set) on the display are really cool. The app syncing features are easy to navigate. Not sure if it will be viable for the next open-water competition (don't want the distraction of monitoring data), but it will definitely help with training. These are fantastic!
