A solid, reliable TENS unit for pain relief, but its premium price isn't fully justified by its performance or feature set.
Compex TENS 2.0 Review: A Reputable Brand with Limitations
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.
