A decent entry-level option for those curious about TENS therapy, but its usability flaws are apparent.
Belifu TENS EMS Unit Review: A Budget Contender with Compromises
The Belifu TENS unit is one of the most popular models on Amazon, largely due to its rock-bottom price and long list of features (24 modes, 20 intensities). In our 30-day test, it provided adequate pain relief, and the rechargeable battery is a great feature at this price. However, the user experience is its main downfall. The small LCD screen uses cryptic icons for its many modes, forcing you to constantly refer to the manual. The build quality feels plasticky and we have concerns about its long-term reliability. It's a classic case of quantity over quality.
