I had a Sigelei 150 non TC mod. That mod will last until the end of days. It was my first dual 18650 mod. I have dropped it onto concrete floors 4 or 5 times. In the parking lot a few times. 2 tanks have been destroyed on it during this clumsyness. I have come to realize I was so confident in its durability I just didn't try to be careful with it.
But, since I first got into TC I have preferred iPV's TC over the Sigelei. The Yihi chip simply does a better job I think at guestimating the resistence of the coils as they heat up.
But I just watched a video of this 213 mod and they were boasting some interesting info that had me hoping Sigelei is finally stepping up their TC game. I wish I could find it again.
But here is something I just found on Sigelei's site...
I particularly like this sentence: "As Sigelei we have designed a more accurate way to temp control in which the functions is similar to the TCR on other product."
So they are claiming the TCR setting is not accurate, then go on to explain that the way they have designed their TCR to work is more accurate. Then say they are releasing the Fuchai model with even less accuracy.
Maybe Sigelei needs to just stick with non TC devices. I will be very curious to hear some comparisons to other TC devices. Because I have steered clear of Sigelei TC mods because they don't do TC well. But I have always felt a bit sad because my Sig 150 is like my first love. Which is funny because I just gave it to the first girl I ever dated which was nearly 30 years ago. That and Sigelei mods just look cool as hell.
@Machinist2 obviously bought the Fuchai. When you click the dropdown they have one listed as the "213". The other listed as the "Fuchai 213". The TCR of the "213" is based on Fahrenheit which Sigelei claims is more accurate. The more common use of Celcius is less accurate and therefore cheaper to produce. And that is what the Fuchai uses.
