First ask your Chiropractor for recommended units. If you have a pain management doctor keep them in the loop and ask them about recommended products.
Then you can find some on Amazon, it's been awhile since I bought mine. I have two small portable units, one has a carry case with it, they are small but pack a good punch.
If you go the amazon route read reviews, all reviews, some of the better reviews can be those middle of the road reviews. Take your time shopping.Then once you get it, have your chiro or pain management doctor help you program it...
You can google them also and find them at medical supply stores online.
