What Buyers Like About the TENS AA

Users particularly enjoy these features when they operate the unit:

  • The TENS AA unit runs on a pair of double ‘A’ batteries, making it portable since it does not need an outlet for operation. Rechargeable batteries can be used so the operator doesn’t need to keep replacing power cells.
  • The front panel on the unit flips open to reveal the control buttons, and flips shut again to protect the buttons when access isn’t needed. The protected front, combined with the soft carrying pouch, make this unit easy to keep on your person, even in a pocket. The soft pouch actually turns out to be more useful for most operators than the hard sided carrying cases, which are usually designed to be much larger than the unit in order to carry accessories and extras. The extra size, however, makes the hard cases less useful than this soft pouch.

What Buyers Don’t Like About the TENS AA

Some users would prefer to have an option of AC adapter so the batteries wouldn’t be run down with every use, and the operator could use an outlet when one is available. However, using rechargeable batteries eliminates the problem of having to replace the power cells regularly.
