PEER REVIEWED

The Compex TENS 2.0 is a dedicated pain management device from a brand known for its EMS muscle stimulators. Our 6-week evaluation found it to be effective in reducing pain, with users reporting noticeable relief. The device is well-constructed and simple to operate, with 16 pre-set programs targeting different body parts and pain types. However, its performance is comparable to devices that cost significantly less, like the Oxiline TENS XS Pro. The primary drawbacks are its high upfront cost, the use of disposable AAA batteries instead of a rechargeable one, and a lower number of intensity levels compared to top-tier competitors. While it is a dependable device, it struggles to provide compelling value in a crowded market.

Alternative Devices

While a quality product, the Compex TENS 2.0 is outmatched on value and features. The Oxiline TENS XS Pro is a more powerful and modern device for less money. The iSTIM EV-805 offers far more versatility (TENS+EMS) at a fraction of the cost.

Testing Methodology

Participants with acute post-surgical pain used the device daily. Pain levels were recorded pre- and post-treatment using a numeric rating scale.

Medical Review: Clinicians acknowledge the Compex brand's reputation for quality, but many suggest that for TENS-only therapy, other devices offer more features, greater intensity ranges, and better overall value. The lack of a rechargeable battery was a common point of criticism.
