Let customers speak for us
Excellent customer service and competitive prices, highly recommend to anyone and I will definitely be using water world sports again!
Great price and quick delivery
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 service :)
Great service from order to delivery thanks
Best price in UK
These boards are avalible from multiple suppliers, however water world sports were very competitive and had great delivery options.
Simple task to select and order from a clear and concise web site and in addition a Very prompt delivery.
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!
Boots exactly as advertised in length.
Many thanks
Had a couple of items from Waterworld and both have been competitively priced and delivered in a very quick time. I'm happy so far.
Thanks for dispatching my goods quickly. All arrived as promised.
