"OK...Harry broke his arm the day before catching the ferry for 2 weeks in France. A holiday where everyday would be spent on and in the water...we were so upset!..Fracture clinic recommend an alternative brand. Luckily i looked at all products and ordered both...next day from Amazon. If i'd had listened to the nurse then no way was that cast staying dry. However, your product was awesome, 100% holiday saver. Jumping off rock, paddle boarding, swimming and snorkling...he could do it all. Thanks to you guys...well done."
