"Our daughter fractured her wrist 5 days before our holiday to Walt Disney World in Florida and was put in a cast. We were devastated that she would miss out on all the fun but then we discovered Bloccs. This product is absolutely fantastic and it saved our holiday completely. She wore it for swimming at the water parks and in the pool over a 2-week period and it never let a drop of water in on any of the occasions, cast stayed totally dry, we were amazed. It really is watertight and very reliable. She also wore it on all the water rides and it was very useful for this. Thank you so much to Bloccs who advised us on a suitable fitting and arranged next day delivery with no fuss at all. If you find yourself in this situation, please do not hesitate to use this product we can't recommend it enough."
