Although I hate to admit it, having a pair of weak knees seems to come effortlessly in the 40s Club. ?? And I need to sit down and rest my legs more often, especially after housework and exercise. My legs and knees feel achy and sometimes painful. When I got to know about Ebene Bio-Ray Extra Strength Knee Guard, I decided to give it a try. Infused with Japan Therapeutic Technology aka Bio-Ray and extra Tourmaline, it provides heat therapy to relieve intense knee pain by promoting better blood and oxygen circulation and firm support around the joint. It is easy to adjust the 3 velcro straps to find the best fit around my ankles, not too tight or loose. If you\'ve thick thighs like me, you will understand! Within 20 minutes of strapping on, I could feel some tingling sensation and some heat therapy penetrating my skin. It says after 1 hour of usage, the temperature around my leg will rise to 37°C. Personally the heat is quite intense but acceptable, just like soaking your legs in a warm bath. When I took off the straps, I could see some redness on my skin due to the heat. Once I stretch my legs, I could feel my joints getting lighter and less knotty. My leg muscles also less tight and more relaxed. Sounds great, right? The instructions say I need to condition my legs to the product and night or prolong use is only allowed after that. Nevertheless I only strap on after I wake up (to warm the legs) and in the evening after a long day (to relax). I\'m the type of person who sweat profusely so I don\'t feel comfortable to wear it during my exercise (the neoprene material feels itchy when I sweat). But I do put them on when I spend long hours in the kitchen or ironing. After 1 week of using Ebene Bio-Ray Extra Strength Knee Guard, I can recommend that you try it for better knee support and pain management. In fact it will help to reduce inflammation and swelling after an injury, and ultimately speed up healing.
