I got these wheels 6 months ago and am very happy with them. They are very light. They make pushing easier due to the rubber web between the pushrim and the wheel which provides a good grip plus a soft springy surface to push against with the thumb. In addition, there are tight doorways that I can get through with these wheels that I couldn't with my standard pushrims, because these pushrims will compress 1/2" to 1" or so (overall) to squeeze through a tight space.
I think these are the only wheels for me from now on.
