Buying Guide: Key Purchase Considerations

- Channel flexibility: Dual-channel units allow independent control for two areas, making scheduling and intensity management easier.
- Pad longevity and adhesive quality: Look for pads rated for multiple uses and adhesives that resist peeling after sweating or showering.
- Compatibility: Ensure pads match your device’s connection type (3.5mm snap or 2mm pigtail) and check brand compatibility to avoid wasted purchases.
- Portability and battery life: For travel, prefer slim units with rechargeable batteries and included pad sets for on-the-go relief.
- Safety considerations: Consult a clinician if you have pacemakers, epilepsy, pregnancy, or other medical conditions. Avoid use on certain areas or during activities that require concentration.
