Quick Fix Heat pad complications

Hi friends....i am getting ready for a pre-employment test on tuesday (5/23). and am going to use quick fix for the first time. I plan on using the Heat pad given to me in the package of quick fix. In order to test the method out i used some hand warmers from Wal mart as suggested on the board. i placed the heating pad on the side of the bottle without the temp strip and put it under my nuts as directed by many posts. i took the temp every five minutes for an hour an a half and the urine itself peaked at 102 degrees. My question is 102 an ok temp to be turned in at? or if i put the heating pad on the box on the bottle as directed...place it under my nuts....let it sit there for an hour and take the test....is the pad pretty fail proof? i have a digital thermometer at disposal to check before i go in. sorry for the bother guys i just want to make sure everything goes smooth thanks guys ill let u know the results
