Tested - and found dehr well ... I am not an experienced scuba diver, only a Hobbyschnorchler. The fins have reliable with me in front of so many Atlantic coast in each bay, sometimes remotely even close. The propulsion rich for 2 people to swim in swimming sporting way to counteract unpleasant currents in the surf area. The spectacle offers a very pleasant viewing area, darkens at any point in any way from, and fits perfectly on my slightly narrower Gesichtbereicht on. I would buy this set again.
