Upgrade Cold Laser Therapy Device, 2-in-1 Laser Therapy Device (4x808nm +12X650nm), Red&Infrared Light Therapy for Deep Tissue, Joint and Muscle Care Fast Recovery-White

The device produces a subtle tingling, pinprick sensation. It seems to help aching muscles, and I did feel some muscle twitching after use.

First of all, it is a beautifully designed product, pleasant to look at, well-engineered, functional, and easy to use. Have it for 4 days. I used a smaller product before, so I know it works. This is more powerful. After the second day, I felt it worked. Use it on my shoulder, knee, and back. After about 40 minutes, altogether battery goes to a minimum. Needs about 2 hours of charge, so it is OK. So far, I am really happy with it. On max laser setting, the metal part stings the skin. Be aware.

I honestly had my doubts whether or not this would work or if it's just a modern day snake oil treatment. I had a large bruise on my arm (probably better 3 and 4 inches in diameter) from a minor scooter crash. I did a couple of 5 minute treatment sessions on one area of the bruise and left the rest of it alone. I'm not sure if it was the laser or just a fluke, but the areas I treated actually healed noticeably faster.One thing of note, the TENS aspect did sting a bit. Set on Level 2 (there are 3 levels, I think) it felt kind of like getting popped by a rubber band. This kind of surprised me because I have another dedicated TENS machine which tingles a bit, but doesn't really hurt.

This device really helps to relieve pain in my back and shoulders. It took about 3 days of daily use before I started noticing reduced pain levels. I use it every night and it is reducing the severity of the pain which then allows me to sleep comfortably. I think the price is good.

The main thing is that I feel like this helps with specific pain points that I have post-workout. That said, it’s not immediately apparent after use, and it’s somewhat less comfortable to use than I expected. There is a slight sensation that I can only describe as constant electric shock at the point of contact, and that’s when I use it on the lowest setting. However, it’s not very painful and it’s easy to get your mind off of it for the 10-20 minutes of use.

This is a neat device and seems to help. It has red light and also offers electronic pulses to help with pain relief. It has plenty of battery life and is easy to use.

Seems to be a decent product. I like that it combines both light and TENS therapy all in one! It's a bit expensive but I think it works fine. This is a pretty good product. I tried a bunch of products and this seems to be as good as all the others that I've tried. Based on the price and the quality I can recommend it. I didn't have any issues with it.

The media could not be loaded. This is a great device that comes with multiple accessories to help keep the device in place for a long time. It feels nice and tingles.
