John S.wrote a review of QM Sports Care Antifriction Plus Cream on February 12, 2016
Familiarity: I've used it several times
Bought this because it was on sale; I've used it on about 3 or 4 rides so far and it works well. The description's right - no cooling, no tingling, just sits there unobserved and does the job. The longest ride I've taken with it so far was about 45 miles, so I don't know how it'll do at 100+ miles, but initial indications are that it'll be fine.
A note on consistency: the label calls this a cream, but it's really more of a thick gel or paste. Imagine very thick Vaseline and you'll have a good idea of what it's like. I was used to using creams like Buttonhole or Chamois Butt'r - this one's a significant departure in texture from those. After application, you'll need a little soap and hot water to get it off your fingers. But it works really well, and seems to be long-lasting.
