im excited but quite nervous also , for me personally after buying the batteries and adding the shipping to the uk it came to $165 which for me personally is a huge outlay. my current device cost me only $30 ( and thats from a uk supplier who we all know are far more expensive) so its a big outlay for something i know very little about .
As long as it's the newer switch you should be fine. MrsCasey had to lick her finger to get it the old switch to fire. He's been making them with the new switch since at least 8/2011 I believe so you should be getting the better switch.
