- How is a dual-channel TENS unit different from a single-channel one?
- Two channels drive two pairs of pads, so you can treat two areas or cover a larger zone at once. Single-channel units run one pair only.
- Can I use it on body areas other than the back?
- It is marketed for back use, but TENS pads are commonly placed on other large muscle groups. Avoid the head, chest, front of the neck and broken skin.
- Who should not use a TENS unit?
- People with pacemakers or implanted electronics, pregnant women and anyone with heart disease should check with a doctor first. Do not use it on undiagnosed pain.
- How long do the pads last?
- Pad life depends on skin oils and storage; most users replace them after several weeks of regular use. Keeping them on the plastic film between sessions helps.
- Does it come with replacement pads?
- Check the box contents for the pad count and electrode cables included. Extra pads are sold separately and are worth having on hand.
- Where is the iHealth Soothe Dual-Channel TENS Unit cheapest?
- At Best Buy, for $39.99, as of our latest check.
