Why do you keep saying no issues, there are certainly issues with the 213.
If you hit the button when the screen is going off it misfires.
The screen text can jumble.
Workarounds must be employed for usable temperature control.
Out of more than 10 reviews and 200,000+ views on Sigelei 213 reviews there are no complaints on YouTube abt these devices. The complaints are being magnified by people who are repeating the complaints of others btw Reddit, VU and ECF...not people who actually have had any issues. i.e. FUD.
Not sure abt the "screen going off issue" is actually an issue. I cannot replicate on my two devices. People said if you fire the button again 13 seconds after you vape it misfires....have not been able to replicate here.
Never had my screen jumble and I've been using them for more than a month...knock on wood!
There are two different Sigelei 213s, the Sigelei 213 which uses F/TC scale and a Sigelei 213 Fuchai model which uses C/TC scale.
If you go to Sigelei for your particular wire they give you the TC number for your wire, which is allegedly more accurate than those published for C/TC. If you want to use the C scales no problem, just buy the Fuchai version. I agree...they should have included both scales in each model due to the resistance of people to use new technologies, but it is not that it is not working.
If there are any "issues" they are not as bad as the DNA/Reluex systems that cannot fit a std 510 pin on an atomizer.
