Should I get a wired or wireless TENS unit?
Reviewer consensus
Wired dual-channel units like the TENS 7000 and Belifu tend to deliver more power and longer battery life at lower prices, and dominate verified-purchase review counts. Wireless app-controlled units are more convenient for use under clothing or at work, but reviewers flag shorter battery life, occasional connectivity quirks, and higher prices.
