I don't know about that brand, but the ZooMeds w/ the adhesive backings take around 8-12 hrs. to get up to operating temps. I also recently acquired a Fluker premium heat mat. It comes w/ no adhesive. you attach it w/ scotch tape on the bottom or side/back outside the tank( glass only ). It does not get any warmer than 100 degrees F on it's surface, and with 3/4 to 1" of substrate, it does a great job of keeping the temps where they should be.
