"I have used my Fly LegsUp on internal flights in Australia and most recently a trip to Orlando from Perth. I usually don't sleep well on flights and my legs (calfs) feel like they want to explode at the end of such long haul flights. Since using Fly LegsUp I have no back or leg pain and slept so well on all flights. I trust the product so much I have sent one each to my mum and sister for their trip from London to Perth next month. Highly recommend as my mum and I are both high risk for Deep Vein Thrombosis (DVT) and my sister has severe knee problems. Also using the large cushion, slightly deflated, is a great way to keep the blood pumping through your legs when you are awake. Great job guys"
