I dont remember who said it but i built myself a rack and was having big problems getting my temps right in the tubs becuase the flewatt wasnt touching the tubs all the way so my temps were off, and someone suggested to get a temp gun and who ever you are thank you becuase now my temps are perfect. THANK YOU my babies are now safe and i can sleep :D:D:D:banana::banana::banana::banana::banana:
