Not comfortable, chose Vital Salveo Train Tec instead
I was confused about which product to buy because the descriptions are very similar.  The seller said that the Train Tec S Pro has more compression and was more appropriate for athletes, whereas the Knee Tec S Pro was more appropriate for daily wear.  I bought one of each of the Joint Tec S Pro and the Train Tec S Pro, because I was unsure as to which one would suit my needs.  I wore one of each on each knee for several hours while doing kneeling, crawling, walking, sitting, and squatting.  I found that the Train Tec is more comfortable, flexes more naturally with my movements, and looks much smoother under my tights.  I do not detect any difference in the feeling of compression, tightness or stiffness between the two products.  So, I returned the Joint Tec S Pro and ordered a second Train Tec S Pro.  Both products seem to be very well made of good materials, feel soft enough on my skin, and very breathable.  I like the gel pressure pad (same on both products) to cushion my knee when kneeling on hard floor.
