Dot review

A genuine contact device rather than a small panel, which is the right way to read its specification. Judge it on surface output over a long wear, not on a six-inch reading.

What we like

  • Sticks to the skin with adhesive rings so it treats while you carry on with your day
  • Rechargeable and pocket sized
  • Seventy nine dollars

What to know

  • Hooga's own page contradicts itself on warranty, listing 1 Year Warranty in the specs and 2 Year Coverage in the badge
  • This is a contact device, so the 120 mW/cm2 figure applies at the LED surface and collapses within inches
  • 19 LEDs cover a coin-sized area
