I'm sure it has probably already been asked and/or answered here, but how does this thing do in straight wattage mode? I do not use TC anymore, as I've found my sweet spot with Nichrome 80 fused Claptons. Mainly interested in the device for the small form factor, and 30mm Atties fitting flush. Also, where is the best place to pick one up at the best price? Thanks in advance!!
Yes it does straight wattage. All the vendors are selling them at the suggested retail price, so you won't find any on sale. Varitube is a good vendor to buy from.
No there is no TFR range option, there was supposed to be but they never implemented it. tbh now that I really think about it this mod has the worst TC I've used in years, I'd set it, and something like going outdoors/indoors would screw it up... It made it so I couldn't take it out of the house. Even found myself wondering if I should try locking the resistance.
I just really liked the idea and look of it so I wanted to like it.

For those who have a G class, may I ask a question please? Can you turn your device off, and after a couple minutes, a shadow, like a ghost, a very very low light version of what you last had on the screen will appear and stay there.. Almost like a burned in image but not, as the screen is totally black when first turned off, and then it just "comes".. if no one else has it, i have a faulty one, so would be great if you could check. Since i can't seem to update the FW OTA with BT on this one (it seems only the Q can do that), and i don't have access to a win machine yet, I haven't been able to get the latest firmware yet.. I am on the second latest, not the initial release, but the V 4.3 from 16th Feb 2017.. the latest is 5.5 which is from 2 months later... Will upgrade it as soon as I can get access to a win machine.. or *should* i be able to upgrade it over the BT app?
You have to 'lock resistance' on Yihi mods if you want to use TC.
That's the 'push joystick straight down until you see the resistance shown' thing that I so loved.
Straight down mind you. Not a hint of being off dead center.
With that, I wasn't seeing the 'Best TC Vape Ever', I kind of prefer the vape I get from my VT133/167 but that may be because of the curve I can load with those.
That's awful... I haven't needed to lock resistance for years, the whole point of TC is the variance in risistivity of the wire allows the board to guess temp, locking it means the board is not actually doing TC.
That's the way yihi boards have always done it. You have to lock the base resistance.

I know but then I have to lock/relocking whenever I go in/outside, it should just read the lowest resistance as the baseline like all the other boards do. It's too much work.
Actually I think it does, just not accurately or something.
Most boards have an autolock/read of the resistance in TC mode, Yihi doesn't. You have to lock the room temperature resistance. You don't have to unlock it though. It compares the room temperature resistance to the rise in resistance as the coil heats up to calculate the coils temperature just like all other mods do. The only difference is you have to manually lock it when you screw on the atty while the coils are at room temperature.

With all this talk of the UI being wonky and some hate for the joystick I guess it is all preference. Personally I find the joystick a welcome change from my 3 other Yihi chipped mods.
For everyday vaping I can make all my changes using the joystick and hardly ever have to 5 click the power button to get into the menu. Is it different. ...yeah but now if I use my Boxer with the older Yihi chip in it it is cumbersome compared to the G's joystick. I hate having to cycle through the menu now to change my temp then clicking the fire button to exit the menu and hope I don't pass by it and have to cycle through again. With the joystick I just press it until the temp is highlighted and adjust from there. If I want to switch from TC to power mode I just click the joystick until joules changes to watts, easy peasy.

That's the part I have a problem with, it's too much crap to have to do... Ive had it burn my cotton at 400f, and the whole reason I started using TC is bc Im add.
Sorry but I haven't had that experience, at 420 to 430 depending on the build I can vape my cotton dry.

It won't happen if I'm sitting in one place, but as soon as I'm in my car with a/c it screws it all up, especially I've noticed if it's hot w/ a/c on or cold w/ heat on it starts acting up... but that's unavoidable bc I'm always running all over for work and going in/outside all the time.
Gotta say though, this cheap little evic with ArcticFox just works, all the time no matter where I am.
Well, the UI, despite vast improvements over previous Yihi chips, is still awkward and cumbersome. The BT is a flaky, beta app and all the promised customizations are still vaporware.
That being said, I think the G Class is probably the best overall mod out there. Due to the hardware. If you take some time to learn the Yihi way and understand how this chip and how the firm/software operate then I think you'll find the TC absolutely rock solid. It'll track you whisper your vape. It can ramp up high voltage amps effortlessly on near dead batteries. This mod is a precision work horse. Only mod I use anymore. Love or hate I suppose...
But that's why I use it. Once I'm setup for a build I don't have to adjust anything, no power twiddling, no temp adjusts, nada. I only need the fire button to unlock and vape. That's it and it's prefect as my wicking allows. Vape 'em dry to the bone.
Also btw, with some setup effort, using the SXi-Q software you can configure any power or temp curves you want; or even both together at the same time for those truly custom preheats on complex builds. Want that mech punch and smooth fade in power mode? Just draw out the graph you want and store it in one of 5 memories for one in 5 coil config/profiles.
There's quite a lot this mod can do that gets overlooked because of Yihi's convoluted software. At last they have been making releases and it is improving. So hopefully they can beef up the UI and usability. This chip is capable of performing any software "feature" of anything out there.
To each their own...
I just wish the ui was better. I hate how all these devices are all so complicated. The ui is not intuitive. I don't have any issue with the device itself, although, I'm not 100 percent sure Tc is working correctly. I replaced my wick today because I was just getting burned taste, looked at the wick and it was charred black,which should never happen.
Yihi is not known for delivering on promised functionality. There is alot of possibility but because they won't open source the software and allow the community to start improving the software, we have a crippled device.
It is the least fiddly temp control I've used. I'm going to pick up a dna 250 device and see if it performs better than my G class or older triade, which I thought had a 250 chip but is only a 200...

I could talk all day about this mod. Mostly good things. But, I won't. I will say that I have no problems with TC. SS316L, single coil, around .60 ohms. Around 30 Joules, 440F. I only have slight burning on the outside of the coil after a few days of vaping. I get the coil gunking up, and need to dry burn. Wick itself seems fine. TC was just as good as my DNA75 device, if not better. Much better than my two other devices that I've used for TC.
Anyone running in the 120-130 watt range? What kind of battery life are you getting, with what cells? Thank again ECF!
