Sorry to hear about your "micro problems". My Highpoint seems to be working fine. But I only used it about 4 or 5 times this year.
One time it seemed to take longer than normal to heat up something but then the next time it seemed to work fine.
Let us know what you find out. Perhaps there is an on going problem with them?
