Cold Laser Therapy Device, Portable Red Light Therapy with 4pcs 808nm and 16pcs 650nm, Near Infrared Laser Therapy Relieve Pain and Accelerates Wound Healing for Pets Dogs Horse Cats (Blue)

It is difficult to be absolutely sure - BUT the light does seem to warm up the deeper layers of the body, and it does seem to reduce the pain and swelling. No negative effects seem to be occurring. The price is decent and the battery lasts a long time and recharges quickly.

I decided to return this item.

I haven’t had it very long but it seems to work well. My shoulder and bicep do feel better. Time will tell more.

Well it feels very nicely made! Being new to using a cold laser it takes some time to figure out exactly how to best use it. The charts in the instructions are very helpful for determining ‘dosage’. One thing I’m learning is that I need to be more regular with its use. The little I’ve been using it I can feel there’s a difference, but it’s likely much slower to help and recover than if I used it more regularly. The included safety glasses seem to do a fairly good job as well.Generally speaking you need to get the opposite color lenses than the color of the laser/light being used. In the case of this device it is red light and near infrared so the blue glasses should be appropriate. You can see from my pictures that it nearly fully mutes the red light. And it has a decent impact on the near infrared.Overall I really like it and think it’s a good deal. The instructions are great as well and it is super easy to use.

Absolutely garbage, used it for a month and it started to fall apart some lights quit working and it wasn’t holding a charge.

My chihuahua had leg surgery. Took it to my vet and she approved it for use. I have used on my pet and it wirks

Stopped working after a few months with no warranties or customer service

I purchased this device for my cat, she is older and walks stiffly. I have been using it for her daily and have noticed immediate improvement. This device really works and is easy to use. Great investment!!!
