The Back to Basics V3 by Purge Mods is a competition winning mod and is a different animal this time around as it uses the 40a 20700 batteries instead of 18650 batteries.

The button housing is comprised of 3 very strong magnets which ensure a comfortable throw and one hell of a hit and one beefy copper contact pin. The threading on each mod is flawless and they are weighty too, these mods ooze high-end quality. This mod comes with a rugged, hard shell carry case.

PLEASE NOTE: This is a direct battery contact mechanical device and it is strictly for ADVANCED USERS ONLY! Be sure to check your atomizer's 510 connection when using it with this device. If your atomizer's positive pin in the center of the 510 connection does not protrude >1mm from the threads of the connection, your device WILL fail catastrophically. Use at your own risk! This mod does not have a locking mechanism, keep it away from children! Mechanical mods are an advanced user product and should not be used by anyone without the proper knowledge on your battery's amp limit and how to test your atomizer's resistance. This mechanical mod uses very strong magnets in the switch—please be careful when disassembling your mod. Avoid using your device to the point where the batteries are completely discharged. Always double-check the resistance of your atomizer on an external ohmmeter, and ensure that your batteries are inserted with the positive pole facing the atomizer in order to prevent battery failure.
