IMHO it may have some benefit; some being the operative.
I'm not sure I'd spend $198 to find out after my experience with infrared light therapy which isn't the same as this but in similar vein.
The infrared therapy did seem to help one horse some but certainly not enough to merit the $300 I spent on 9" x 11" LED therapy pad
The other horse couldn't stand it on his back and about swished my face off with his tail until I got it off his back.
Hopefully someone that has actually used the product you're asking about will come in with their review.
For my part, I'd be hesitant, considering the money you'd have to spend
