Today I opened up the controversial new Fuchai 213 by Sigelei. I set ramp up to as low as possible so it blasts AS SOON as the button is pushed even faster than the older model Fuchai box mod did. I had never owned anything with as much initial punch as the Sigelei Fuchai "200W" regulated box mod until now. Unlike DNA 200 mods that auto-detect nonTC coils and have a medium level ramp up/heat up time and a punch of 8...it doesn't ever have a burnt taste. I spend $48 bucks on a grey colored model and the aesthetics and construction are a step in the right direction because of it's portability as well as slightly curvy and pleasing appearance. It's gotta be Zinc Alloy and some small pieces aren't but it actually could probably survive a small-small fumble from 4.5ft. on a rug without making a scratch or even slightly affecting the batteries if placed inside. The hatch has a nice stable cover that blends in with the design of it and isn't loose however the insertion process requires care because it's not too snug like some mods I've bought but snug enough that slapping in a pair of 18650s takes more TLC than my RX200S but that's a triple cell machine. I am beginning to think I'll keep the RX200S for it's unique design and reliability I'm sure I can count on being a while since I got it before heavy use of the thing. I have NO idea about how TC options work on this device or if they're working as they are expected to, but anybody out there who is a VW coil user only (Kanthal or Clapton, even SS on certain tanks) lower the ramp up time to absolute minimum setting and plug in a TFV4 with TF-T8 Octuplets for instant clouds that nobody's seen unless they've witnessed this combo or a TFV8 Cloud Beast Kit with the V8-T6 .2ohm Sextuplet coil at a possible max recommended wattage of over 230W but I used 128W and not a watt greater so far. I'm using LG HB6 30amp min. 1500mAH cells and LG HB4 30 amps or more at full charge 1500mAH cells as my backup pair. I am waiting for the LG HD4 cells, not the LG HD2C 18650s because even though my ordered cells drop off or something and lose max performance earlier than another 2100mAH 20-25 amp cell than if it's about as good a VTC4s even mostly...They're for my TFV4 which is new and run the Beast coil just released called TF-T8 octuplet .16ohm Clapton coil for wattages up to approx. just under 150W max for the coil. It blows as much clouds and actually tastes better than the TFV8's Kanthal coils so I'd use a TFV4 tank if you have one and buy that coil until the Cloud Beast coils are more affordable. 20 bucks for 5 TFV4 coil packs is a 5 dollar savings from single at my local shop. So the TFV8 subohm tank isn't a purchase I'd suggest at the moment but the Sigelei Fuchai is my dream regulated box mod. No TC complicated menus, just simple presses to blast off those Cloud chaser specialty coils. Wooooo! Don't listen to the negative comments. Unless you're a TC fan and I'm surprised how many people use that crap. Peace.
