I purchased my first pair of KS1 Vent not long ago to support my knees through exercise therapy in preparation for a double knee replacement scheduled for early next year. My therapist and I both saw an immediate improvement in my strength and ability while wearing the Bracelayer pants. I felt so much more stable while wearing them that I started wearing them even on my non-therapy days! I decided that, if I was going to wear them at least five days a week, I should really have more than one pair! I ordered a pair of KX2 and am loving them as well!
KS1 Pros: tie waist and pocket
KX2 Pros: compression up the thigh and across the lower back
Shipping: absolutely remarkable! I received notification that my orders had shipped on the same day I placed it. They arrived in four business days.
I've already recommended them to a number of friends and some have placed their first orders. I'm sure they will love them as much as I do.
