Had to fill in my warranty replacement form, within 36 hrs after receiving. (using time : 3,5 hr). Am I the new recordholder ? It keeps giving a current temp. of - 10.0 degrees, so the unit keeps heating up (tested with a core temperature meter).
My first BT unit failed in a similar fashion. The display read -17.6, so it kept heating up, then all of a sudden it decided the water temp was over 300 degrees, but my favorite part was this which had me laughing.
