Are budget Amazon TENS units as good as name-brand ones?

Specialist-community consensus is that inexpensive units from AUVON, Belifu and Comfytemp deliver comparable relief to pricier name brands for most users, with several reviewers reporting multi-year lifespans. Name-brand options like Omron and four-channel units like the iSTIM are favored when buyers want stronger output, refined controls or brand-backed support.
