Trigger Point TP Therapy Quadballer 11” Roller Muscle Deep Tissue Massage. Roller/pressure tool for self-applied myofascial release and deep tissue massage.  This allows you to roll completely through the quads, IT band, lower back, hamstrings and neck in a safe effective manner. It is designed for greater precision and control than foam rollers.  Patented material mimics the feel of the human thumb and will not compress after repeated use.  Compact and travel friendly; latex-free construction. I bought it a long time ago and realized this isn’t for me. In all honesty I don’t remember using it.
