    Back 2 Basics V4 21700 / 20700 Mech MOD Kit by Purge Mods

    The Back 2 Basics v4 Mech MOD is the reiteration of Purge Mods' acclaimed and beloved B2B V3, the affordable all-purpose mechanical vaping platform designed to push your cloudage, not your wallet. Borrowing many facets from the previous version, the B2B V4 has a solid naval brass chassis broken only by the 510 threading, firing switch, and an impressively etched signature Purge skull logo. The proprietary magnetic Purge firing switch is the same high performance enabler that comes in every Purge mech mod, endowing this mech the incredible performance Purge Mods is known for. The Back 2 Basics v4 can accept 20700 and 21700 battery cells as well as 18650s by using the included delrin battery adapter.

    Now available in a Knurled Finish with matching Skull RDA!

    **The Back to Basics v4's 18650 adapter sleeve MUST be placed over the positive side of your battery. The copper contact on the sleeve must between the battery positive and the atomizer's positive pin. Do NOT place the sleeve on the negative side of your battery or you run the risk of the mod auto-firing.

    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, so 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.

    1. I wish I would have bought this sooner!  star rating

      Posted by Richard Schneider on 28th Aug 2019

      I've been vaping for about six years. It started out as just a way to get nicotine without smoking cigarettes, but now it's a hobby. I had been wanting to buy a nice hybrid mech mod with a magnetic switch and a nice RDA for a couple years, but just couldn't get myself to "pull the trigger".

      So far I have only had this kit for about five days. I have only used one build in the RDA, which is Coilology SS316L Framed Staple coils and Cotn Threads cotton. I love how this kit feels so well constructed.

      The only complaints I have are minor. I don't like how short the included drip tip is, so I've been using one of the many 810 drip tips I have. The other thing is I wish the switch assembly was shorter. The mod is a little tall with the switch on it, but it's not a big deal. I would like the button throw to be a little bit lighter too, but that's not a big deal either.

      All in all I am very happy with my new mech mod kit so far! I hope I haven't just opened Pandora's Box because I could see myself buying more and spending too much!

    2. Best Mech Mod On The Planet  star rating

      Posted by Dylan Walton on 12th May 2019

      I purchased the Red Knurled model and I couldn't be happier with what I received. The craftsmanship and attention to detail on this mod is above any I've ever come across. The knurling is perfect; not being overly abrasive makes it very pocket friendly. The all copper construction is as solid as it gets and is one of the most conductive metals on earth, attributing to the mitigation of wattage variability. Speaking of which; the switch. I'm getting impossible consistency with this switch. Doesn't matter where I press; this thing rocks every single time. Last but not least is the RDA. I'm running a .2 Ohm dual coil and this RDA billows vape like an oil refinery. I lied when I said lastly. LASTLY. If you're familiar at all with a Pelican case, that's the kind of box this beast shows up in. Best mech I've ever used.

    This product does not carry any warranty and we only guarantee that you will not receive it DOA (Dead on Arrival).
