I don't believe it's false advertising. It could probably be outlined better for people who are new to vaping and aren't used to all the terms, it's easy to be overwhelmed. When something says it's a 'kit', in general it's a mod plus an atomizer. Usually a subohm tank with factory coils. They differentiate those by having another listing where it will say 'mod' or 'mod only' to let people know they're just selling the mod, use your own tank. Using 'TC' in the title is to let folks know that the particular mod in question features temp control, not necessarily that the kit has been assembled to be a tc experience out of the box. You might see ikonn 200w tc mod only or ikonn 200w tc kit. In a way it should read "ikonn 200w tc" and kit, rather than ikonn 200w "tc kit".
The majority of factory subohm coils out there are kanthal which aren't suitable for tc. Only a few are ss316 for temp control use, but then the tank that goes with the kit doesn't necessarily have to support every feature the mod has to offer. More or less it's 'good enough' to get you started. Like just about anything else, they don't kill themselves on giving you the best of the best in an all inclusive kit.
I'd agree with others that tc may not be the best to jump into straight out of the gate. At least get a feel for wattage vaping just to test the vaping waters. Most bakers start out making chocolate chip cookies, no diving straight into handmade baklava or souffles.
I don't know much about the mod in question, I haven't used any recent ijoy/eleaf mods. The tc on my istick tc100w was decent. Not great but it functioned, a helluva lot better than the 'tc' on my alien. Not all mods or their software are created equal, it's possible to have 4 different mods from 4 companies using 4 different chips and all perform differently while they're all claiming to be 'tc'.
No doubt it's frustrating especially being new to the vape world with little understanding of various companies and their products or reputations. Hopefully it doesn't result in 'vaping sucks' as the attitude going forward. It's like anything else though, if I grab a blender for $15 off the shelf at the store and it's weak and the blades bend and it breaks or it blends too fast or slow I can't very well be like 'cooking blows'. Well, the cheap pos I got does in fact suck and that's why there are a ton of different tools out there. A vitamix costs more, does basically the same thing - but it does it a whole lot better.
Personally I don't like factory coils much in general. I got sick of duds, trying to fiddle with them and the high cost so I got into building my own. If there's a hot spot, I can fix it. If it's touching the wall of the chamber and causing a short error, I can fix it. Factory coils are mass produced, costly by comparison and often flawed. Cotton too tight, too loose, coils messed up etc. The concept is great, simple to pop one in and be done with it. In real life execution not so much.
I do mess with vaping a lot more than smoking, smoking was easy. Light and smoke it. There were only a handful of brands out there and they were either menthol or straight tobacco. When switching to vaping I had to find out what juice I liked, the flavor, the vg to pg ratio, the nicotine level. Then the mods, the tanks, the coils. It's worth sticking with it though. I thought I'd smoke until the day I died, but I thought that would continue well into my 60's or 70's. I didn't figure on cigs making me cough so bad I was throwing out my back, passing out and making me cough so horribly I couldn't hardly carry on a conversation without going into coughing fits that lasted 10-20min - before I even hit 40yrs old. With smoking no longer an option it was either try a patch, quit cold or vape. Obviously it's not everyone's situation but the minor setbacks are worth being able to walk to a mailbox without doubling up and heaving, gasping for air.
