The vibrating TriggerPoint GRID Vibe Plus foam roller features high-density EVA foam to provide clinical therapy technology in a compact, portable, and personal unit. Specifically designed with four vibration frequencies ideal for pain relief, the surface pattern of the GRID Vibe Plus replicates the feeling of a massage therapist’s hands to help channel blood, improve oxygen flow, and heal tissue. This vibrating foam roller helps prepare the body for peak performance by helping users relieve muscle and joint pain, and improve flexibility, balance and mobility. Ideal for home use or for rolling on-the-go, the built-in battery lasts up to two hours when fully charged. The GRID Vibe Plus measures 12", has a 3.5-inch diameter, and weights 2.5 lbs.. The small diameter design creates less surface area resulting in targeted, deep tissue compression. Includes an AC charger and owner’s manual with detailed instructions for use. Includes a 1-year limited manufacturer’s warranty. TriggerPoint empowers people of all lifestyles to move and feel better. TriggerPoint designs and develops innovative massage therapy tools that mimic the touch of a therapist’s hands - making their foam rollers, hand rollers, massage sticks and balls ideal for individuals of all ages, sizes, and athletic ability.
