Damn you guys drive far! I just used Agent X this last monday for a new job I just started. It has worked many times in the past for me as well so I don't doubt I will pass this one. They sell it at Knuckleheads which is like 20mins from my house lol. $40 and its good to go. Just make sure that when you are putting it under your sack that you don't let the temp guage come in contact with your skin. That could cause a invalid reading on the temp guage.
