Infrared Light Therapy for Joint and Muscle Pain Portable Rechargeable Flashlight， Red Light Therapy Wand Device，Red Lights-4 Wavelengths，Near Infrared Light Therapy.

My 16-year-old dog loves this, and when he has a treatment, he moves much easier and does zoomies like a puppy.

Probably just a morning that's absolutely nothing.

Not sure if my pain is going away in my joints, with many injuries from martial arts, but it definitely is warm and easy to recharge.

Love it! I use it for TMJ, hand and wrist pain, and tooth and gum health. It's very powerful--I shine it through my cheek and it goes through my teeth (I figure it's not so drying that way, as I can swish my saliva while using the light). Very happy with this product, especially for the price I paid.

This red light therapy flashlight is made of aluminum and feels well-made and durable.The light comes in a nice sturdy plastic box with its rechargeable battery and a charging cord. NOTE: the wall charger is not included.This light puts out four different wavelengths of red light.It is a nice flashlight that produces four wavelengths of red light. Great to use when you don't want to ruin your night vision.Does it reduce pain? I'm not sure. I've tried it on my knee for a couple of weeks and I can't tell the difference.The light does get hot. I only use it for about five minutes at a time. I suggest getting the proper sunglasses to protect your eyes.Nice light, not sure if it reduces pain.

I feel it works on my wounds. Great price for a little flash red light. I love that it can be recharged with a c-type charger!

it would be a better product if there were four Leds instead of two because two Leds don't produce enough heat to stop my pain

It is a sturdy light it came in a nice plastic case.
