Well I already returned it and I am looking at a better brand to buy, I get paid next weeek so it will be pretty soon when I buy it. The problem with the dimmer switch or rheostat is I am out of the apt a lot and the tempurature fluctuates a lot, for example yesterday it was 75 degrees outside and now it is 29, that cold front hit oklahoma hard, on another note I am looking forward to the 7-9 inches of snow we are supposed to get tomorrow.

Anyway back on topic, I dont have time to moniter the temps that closely so a ranco or somehting similiar is on the way, lesson learned
