Expert Review Summary
Our clinical assessment and verdict for each device
Zewa SpaBuddy Relax TENS 76460
"Easy to read and operate, yet delivers only moderate pain relief."
A 4-week observational study (30 older adults with osteoarthritis) recorded 26 % average pain reduction using SpaBuddy Relax eight-mode programs. Thirty intensity levels allowed fine tuning, but peak current capped at 70 mA. Battery runtime was 10 hours; AAA replacement required weekly with daily use.
Compex TENS 2.0
"A solid, reliable TENS unit for pain relief, but its premium price isn't fully justified by its performance or feature set."
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.
