Much better than a lacrosse ball
I got this to target errector spinae muscles, and for that purpose this is a excellent product, although care must be taken to ensure you do not injure yourself.  The supplier provides videos with treatment suggestions, although I prefer to use this intuitively.  Because there are two contact points and this is wheel shaped, I experience much more stability and control than I get with a lacrosse ball.  Additionally, I think I am able to target muscles better because one wheel can be where I have a knot, and the other provides support.<br /><br />Anyway, the blue wheels are firm with little give, but they are grippy.  The entire apparatus is sturdy and well made.  It allows me to take myofascial treatment into my own hands, and has already paid for itself.  Recommended to anyone who suffers back or neck pains.
