I like mine so far. I do need some better batteries though. My only gripe about it would be the button. I wish it just had a normal button on it. The side fire bare isn't really a side fire since the button is actually at the top and the bar is hinged at the bottom. Also the tank for me is useless. Not that it is bad, just not in my wheel house. Big huge tip and a .25 5 coil head, really? I am pretty sure anyone doing this would probably own a decent RDA RTA that would work better. The heads do like they would be easy to rebuild though. I will try at some point with the 3 coil version and see if I can lower the resistance some so it is more to my liking.
Menu system is easy to use, love the auto flipping screen. Lots of options and information too.
I pretty much mirror everything Phil B. said in his review, that usually ends up being the case with me since we have similar vaping styles.
I have had no issues with the internal charger. I use it mainly because the built in charger is better than the crappy trust fire external charger I have.
Still not completely sold on temp control yet either. It is hit and miss with me. I don't get consistent vapes with it. Sometimes they are underpowered, sometimes over powered. Could be my batteries, could be my builds, could be a wicking issue. Batteries and juice don't seem to last longer either. It is great for a dripper though, no dry hits when you run out of juice. I am not giving up yet. I am going to get a Siren MTA and some stainless wire and see how that goes.
I can't speak to how it works at higher wattages because I simply don't do that. I think the highest I have ever used in my life is 50 watts, and that wasn't for very long lol.
