exo terra heat mat temp

[francojs]

hello everyone, i installed a 16W exo terra medium desert heat mat

i put the probe between the mat and the glass i am exactly reading from 35,4 to 37 degre celcius, (95.7 to 98.6)

i need your quick input to see what you guys are getting with the same product.

i thought i would get a lot more from the heat mat

which is giving me a temperature in the tank of 23 celcius (73.4)

am i wrong? the heat mat is not there to heat the tank right?

maybe i got a 8w heat mat, all the boxes were opened at the store..
