They work great.
Get a comb riser, not a cheekpad.
Get one with the darkest brown leather and eyelettes that you can. They really blend well with the rifle.
Do not tie it on with a rawhide thongs. Looks dumb, gives a thick seam, and hangs down too much.
Use a dark brown shoe lace. Tight in on tight, just like a shoe, and make sure that the sling post of the butt stock sticks up through the last two sets of grommets, so that your tying knot is on the back side of the sling post.
If you do all of this, it will stay on tight, and won't slide forward, backward or around. As the leather ages, it will dry somewhat, and get even tighter.
I had two, that stayed on the rifles for years, with no adverse effect upon the wooden stock. I did not oil the pads, as they only rarely got wet and weren't out in the scorching sun.
Hope this helps.
