This product may be expensive, but it's the best one I've found in 3 years+ of looking for relief.
I've had problems with my knee locking for about 10 years. I've been on all kinds of muscle relaxants and pain killers but they didn't do anything but put me into lala land. I've had arthoscopy with meniscal cleaning but it only relieved the locking until I went back to work--about 6 weeks. I've tried all the arthritis labs and knee supports out there.
I tried this through a free trial offer and was hooked. It took about 6 weeks to reach full effect, but my knee has not locked up in a year and I haven't worn any type of support in 6 months.
The relief of pain and emotional relief alone are worth the cost of this product--I won't be without it!
