This one is a very good box mod. Build quality is OK, paint job not the best, has some uneven painting over the edges. Battery door moves a little bit. Atomizers sits flush, making a very good connection. Right now I am using it with a Kayfun V4 in TC mode, works flawlessly. The capability to adjust TCR manually is one of the best options, making it really easy to use it in TC mode with every capable wire. Right now I have a 430SS build, TCR set to 14. After battery change it keeps all the settings in memory, including TCR. New coil question only if I change the atomizer. No new coil question after deep sleep. Just press fire button and vape on. As for setting up TC mode, first you have to set the max wattage, set TCR, set desired temperature and put atty on. The rest is made automatically. One annoying thing, when using it on TC mode and wanna change the watt settings, after going back to TC mode needs readjustment of TCR. But once max watt settled for your own taste and everything else set, is like vape it and forget about it. My current setting is paired with a Kayfun V4, genuine gold plated spring, 0.83ohm, 430SS wire, TCR at 14, °C set at 270, wattage at 21 and it vapes like a boss!

Very good material, very good fitting, very good build quality. It is not heating up during vape sessions. Recommended.

Build quality is very good, no issues. Fitting is OK, no problems over fitting whatsoever. Having a Teflon coat means it won't heat up during longer vape sessions. The color is very good, pleasant and giving a different look.

After battery change it keeps all the settings in memory, including TCR. It only forgets the atomizer, so it is asking for new or old one. Just press on old and ready to go. As for new coil question after deep sleep, it occurs after not being in use for a couple of hours, that is not annoying at all, it happens once a day, in the morning, when I woke up.

Easy to coil, hard enough to not to destroy your coil while inserting cotton. Arrived clean, no issues whatsoever. It can be used in VW or TC mods (TCR adjustment needed in TC). Good quality.
