I took a long time considering purchasing magic5 they’re not cheap and I had heard mixed results. I finally took the plunge and when they arrived I was surprised by the fit, which is quite different from other goggles. I read all the information about wearing them much looser than others and it took many swim sessions to adjust correctly. I felt too loose and they leaked, too tight and they left uncomfortable marks. Customer service are second to none! When I explained my issues they discussed where the goggles leaked/where there was pressure and sent out a new pair with extra cushioning and I’m much happier with this pair.
