hey vespid....how do you like your 213? I bought one too, but it doesn't seem as good as my cuboid or evic VTC mini. both of those devices I use 316SS and set the temp to 400F and get perfect vapes. with the 213 at the same temp its so weak. I have to turn it upto 450F and its still not as smooth and consistent as the joytech stuff. once in a while I get nothing when I press the fire button and have to repress it too, it seems to missfire on occasion. damn thing cost over twice as much as the cuboid but is not as good. the 213 sure looks pretty thou.
Hey DHCrocks,
Sorry, I missed your question...
I
really like my 213. It is the smallest dual 18650 mod that I have seen. It is quite light considering, yet it is very well built and a quality piece. It looks awesome, and it preforms adequately. I say adequately, because I do think it could use some improvements in the TC pre-heat department. This can be overcome with some fiddling. Other than that it rocks!
I also use 316L SS for TC. I have found that the key to getting a good TC vape with this mod is adjusting the pre-heat setting and the temp setting. I manipulate these each time I change the coil. The settings I use for 24/28 SS clapton coils aren't the same as I like for a regular 3.0mm ID 24 or 26 SS coil. I usually keep the temp between 400-440°F. But, in my opinion, the pre-heat adjustment is the most important.
Note: I have heard several people in reviews say that the temp setting overrides the pre-heat setting. In my testing, this is not true. So, say you set the temp to something very low like 300°F and set the pre-heat to something relatively high like 80W @ 9 seconds. In theory, the temp setting should kick in almost immediately, override the pre-heat setting, and prevent getting a dry hit or burning out your coil. In reality, I have found that the temp setting does not kick in until after the pre-heat setting has finished. This is, of course, very very bad! So, you have to be careful with the pre-heat setting. You want to get it set to where it will reach your temp limit setting, but not to where it will radically exceed it.
I used a Yihi SXMini M Class for a year or more prior to getting the 213. In my opinion, the SXMini was leaps and bounds better in TC than the 213. I have never used a cuboid or evic VTC mini, but I would describe the SXMini in a similar fashion... you basically set the temp and get a perfect vape, the pre-heat is handled for you and it works beautifully.
Another thing to mention is that I have found the TFR setting to be sometimes better (for me) than the SS setting. I use the TFR values found at steam-engine.org.
Then we have the whole firmware update debacle. Reviewers and vape shops list the 213 as being firmware upgradeable. However, there is no indication of this from Sigelei themselves. It would be great if Sigelei could improve the TC pre-heat feature with a firmware update. However, I have no idea if that is even a possibility.
