This stick is a great all around stick very straightforward design with a nice tacky surface for hooking onto the skin if you wish. I use this on the bottom of my feet as it has great contact and can be used anywhere for normal rolling as well. The countour stick is better as a roller for light duty rolling but it can't do the MFR feature like this stick can so both have their place that a ground foam roller does not. The Grid stick however doesn't compare to these two sticks, nor a ground foam roller, it tries to hard to be a ground foam roller when it is not.
