Query: excellent product

i purchased this to run a 150w ceramic heat element for my 4 foot ball python.. cant be happier.. keeps the tank at 83-84 degrees perfectly. easy to set up. just press n hold set button.. then select temp u desire and your done. digital readout is also a great feature! gonna buy another for a heat mat.. this thing handles 1000w so im not even givin this thing a workout. great product and great price
