    Bought this when I got my Pulse BF Squonker because i didn’t want to take any chances using a mexhanical mod. This was a boon because it was half the
    price of other build platforms with an ohms meter and also shows battery voltage in the burn test mode. This is great as it lets me test my 18650 batteries too. Can’t fault this it made my first build a complete success!
