I've got them on my RS as well. I ordered another set last week which came yesterday. I placed the first set too high on the side of the tank, thus the inner area of the knees are barely catching them. Mine look just like the link, they are placed too high to be of much use though.
I'll wait till it warms past 80F to apply the second set.
