Nice glasses

I have lost quite a bit of contrast vision (54 years on insulin probably to blame). These have made it easier - much easier - to follow a golf ball's flight in the air. Sadly not always an unalloyed pleasure! But that's not the glasses' fault! Good pricing and quick delivery. 👍⛳️🏌️‍♂️

Great company, very helpful

Very pleasant dealings with Waterworldsports in the purchase of an inflatable kayak. Not a monumental spend but sales, service and shipping are second to none. No extra cost shipping to sunny Northern Ireland and customer services quick to respond to a couple of small queries..many thanks..

Quick delivery. My first foil kite, well made and easy to fly. Handles gusty conditions and delivers a good amount of pull in strong winds but not overwhelming. Loads of fun for beach holidays!
