Okay so I'm just enjoying "beast" coils recently released by Smoktech for the TFV4 Subohm tank 24.5mm diameter size-my favorite tank still and even more so and here's the reason: TF-T8 .16ohm "Beast" Cloud Chaser family (of their coils which are categorized) Clapton coil which can cloud up my entire condo in 3 hits. The wattage I'm enjoying is 118W or 120W depending on if I'm giving utterly ridiculous vapor production the greatest demonstration. However, it can max out at 180W. My Sigelei Fuchai 213 handles 130W when I vaped the coil at that level so that's enough for now. Otherwise I'm charging HB6s for the new Reuleaux RX200S which is updated to 250W as of 7/4/2016. I'm finally using my DNA 200 mod because the settings I have applied are FINALLY appropriate for Kanthal & Clapton auto-VW vaping. I know there is a CSV Kanthal file but I don't know what the manufacturer is even friggin using. Out of 2 choices of Clapton wires, 4 different Kanthals, and the shape and measurements I would not know-ever. So this discontinued Hcigar VT200 200W DNA 200 mod is about 1100mAH built in cells that charge quickly, with the current firmware having a perfect 25/26 continuous amperage, ramp up time options that rival the Fuchai's, and all sorts of features that the Escribe software for Windows (I build high end/multimedia Windows Desktops for 45% more affordable than any completely identical build [down to the brand of the RAM sticks BTW]) but it's a game of trial and error that when you're not using the TC feature which the chipset basically was made almost exclusively for-custom TC options galore-so I gave up on the mod for a while. At this time it's not available, but a VT133 or something or other is it's replacement and I'm guessing it's not 200W capable by the name. If you find one of the discontinued 200W Hcigar DNA 200s buy it immediately. Lavabox is a piece of plastic with a 115 dollar chipset made in the United States but probably shipped out of the continent for assembly of the mod enitrely. It's solid, smaller than and dual 18650 but substantial in size for big hands like my own, has one of the best Lipo packs already installed in the stock model, and is truly capable of anything. The solid as a rock construction and gold plated perfectly designed 510 pin connection, simple menu, and ironically was formerly the most desired and most affordable of the DNA 200 mods at the time it was sold. I got my new replacement TFV4 Black Stainless Steel and Pyrex over-sized tank and the brand new coils from Smoktech for the tank and am thinking it has everything any type of vaporizer user would love once they learn the software. The RX200S is slower to ramp up but the tank plus the RX200S base is sturdy when placing it on a table near your work station and has a different vaping experience which I also love so Just reminding people that if they look around ebay or something for an unopened device, they would be hitting the jackpot. That is all.
