Bests & Worsts Reviews from Amazon

I just bought this as a second unit to use at home. It's the most affordable and versatile TENS unit with 5 different settings and an easy 9v battery. It's light weight with a convenient belt clip. I ordered the second one so that my wife and I can use them at the same time or I can treat multiple areas at once. I use this to treat lower back issues due to a bulging disk (helps with the muscle strain and spasms, but will not reduce disk swelling), sciatica, and a rotator cuff injury. I've found it greatly reduces tight muscles, muscle spasms, and perceived localized pain. For less than $25, everyone should own a unit. Here's a couple tips to get the most out of it. 1. Wipe off the area with alcohol first. This will take away lotion and oil so that your pads last longer and stick better. 2. Search online for TENS pad placement diagrams. There are a lot of articles and images that will tell you where to place the pads for any problem. 3. Buy a set of rechargeable 9V batteries. I've had great luck with the Tenergy TN141 2 Bay 9V Smart Charger with 2 pcs 9V 250mah NiMH Rechargeable Batteries from Amazon. 4. Buy extra pads and cables. The cables last one or more years, but will wear out eventually or when pinched. The pads can last a month to a year. I like ones that stick well and change pads every couple weeks. 5. You can use cold pack wraps to hold the pads in place and ice at the same time.
