Not bad, but not great

  • Familiarity: I've used it several times

I bought these thinking they were forced air. At the price, I should have known better. These are slip in heaters that generate a small amount of radiant heat out of the toe of the boot only. The car option with 12v is great, but the warmth of the heaters disappears quickly. I would suggest spending a bit more on a forced air heater for the drive up to the hill, however these work to heat the liners.
