"Was worried it would slip during tennis. It doesn't move at all. Played a full two-hour session with zero knee pain. First time in six months I've finished a match without limping."

"I'm 58 and my physio told me to try one of these. Sceptical at first, but after a week at the gym I'm a convert. Leg press, squats, the lot. No aching afterwards. Wish I'd found it sooner."

"Knee was stopping me playing football. Coach recommended a patellar strap and I found this one. Fits under my socks, stays put the whole match. Back to training three times a week."

"45 minutes on the elliptical every morning and my knee never used to make it past 20. With this strap I'm doing the full session, every time. Comfortable, breathable, doesn't budge."

"Bought this after knee surgery because I needed to get back in the garden. Bending, kneeling, lifting. Not a single issue. My daughter couldn't believe I was out there the same week it arrived."

"Ordered two, one for each knee. Did a 9-mile coastal walk last weekend and felt nothing. People always say 'you don't need both' but trust me, if both knees give you grief, just get two."

"Thought it would look ridiculous under gym leggings. You can't see it at all. More importantly, I'm leg pressing again without that sharp click on the way down. Absolute bargain."
