"MR4 lasers are now my go-to modalities for addressing lower extremity injuries that are slow to heal. The devices are typically used on all athletes in the facility, but I always send the portable MR4 ACTIV with any athlete who is traveling or heading to an event. We have seen great results."
Nike Oregon Project Head Coach

"We've used the Multi Radiance ACTIV Laser for months now on muscle soreness and it delivers as promised. We're recovering faster and that means everything in a sport where fractions of seconds mean winning or losing. Plan, Execute, Win...that's Monster Media Racing and now our ACTIV laser always travels with us. Highly recommended to everyone."

"Due to its portability, the Multi Radiance Medical laser has been easy to keep with me on the road and as my 'go to' modality for acute muscle strains or local inflammation."

"I find low-level laser therapy very beneficial for my patients with chronic musculoskeletal pain syndromes, and an important adjunct with other interventions such as manual therapy and therapeutic exercise. Layering LLLT with other interventions such as kinesiological taping and instrument assisted soft tissue mobilization helps reduce pain and facilitate the healing process. I love the portability of the MR4 ACTIV unit and the combination of direct electrical stimulation with the MR4 Super Pulsed laser. Most of all, I appreciate the education and support provided by Multi Radiance backed by research."

"The Multi Radiance Laser has been a primary device in our training room as well as on the road when we travel. We are highly selective as to what we use and what we are willing to invest our time and money in. We will not be without the Multi Radiance Laser System."
