Red Light Device 660nm LED Stepless Dimming Portable Memory Function and Rechargeable Design

Pain relief and vitamin D therapy.

It works but has no timer when it sporadicallyGoes on and off. Not very good looking for a dermatology device.

I purchased this for my dogs neck. I like how it fits in my hand, lightweight and doesn't bother my dog. I subbed my toe and immediately used this, I was surprised how well it worked. The swelling and pain disappeared the following day.

Battery charge lasts forever on this thing. Easy to turn off (though maybe too easy/sensitive button). Nice adjusting brightness, affordable, and gets the job done.

It works when it wants, very low charge, but works great when its on... I had purchased one previous to this one thought it was a glitch so returned it, New one acted the same when you want it on it will light up red and shut it self down... For the price point I would NOT purchase this product again.. A total waste of my money 😑😑😑

Very hard to turn off. Turns on by itself.

Works great and tested the spectrum with a spectral analyzer, it came out to 680 nm which is perfect for improving eyesight. A full review is found on the website cruisingreview dot com.

I was mashing the button down and getting nowhere, then for some reason known only to my spiritual guides, i just lightly touched it and the thing finally went off, just like the guy in the video. It still flakes on and off here and there, but i don't care because I'ive only used it once on my what's turning into chronic knee pain, left it up against the skin awhile, and, mirabile dictu, pain gone, at least for now. I'm planning to add to my collection of these gadgets, going bigger, with more bells and whistles, at some point.
