Some are; some aren't. [How's
that for an answer?
]
Part of the answer lies in not confusing supplier/marketer with manufacturer ... and in identifying the actual model number for the device that is being marketed under a brand name. For example, Totally Wicked sells
four different e-cig models.
1. Their "Titan" (for which they are best known) is a Joye 510, the single most popular model today (at least among ECF members). Scores of suppliers carry it, most using the name "510." Other brand names include Dura and Yeti. And companies other than Joye manufacture 510s. All are compatible with each other.
2. However, you are referring to Totally Wicked's "Mini," which very clearly is a DSE901, and compatible with any other DSE901 (and its battery also is compatible with
Kr8 cartomizers).
3. TW also sells a 10 cm (i.e., 100 mm) "Super-Mini." I was going to speculate that it might be a 98 mm Joye306 (aka Janty Mini Fogger), but that has an exposed bridge atomizer,
not what I see in TW's photo, so I don't know. [If you only knew how much I hate saying that.
]
4. Their fourth model, the Screwdriver, is best left for another discussion. It's a "Mod" and a different kind of thing altogether. In a sense, it's a different (and much longer lasting) battery for your DSE901 atomizer.
Both the Smoking
Everywhere Gold and NJoy (not to be confused with Joye) NPro are the RN4081 and, therefore, compatible with each other. blu and Volcano are both L88, compatible with each other, but not with a DSE901 (e.g., TW's Mini).
* Smoke
Anywhere is yet another supplier/marketer. I've heard of it, but not familiar with them. Their website calls one of their two models the "NPRO" so I
assume [please notice that word] that it also is an RN4081. Their NCIG model clearly is a penstyle, probably the RN4072 and compatible with
most of the other penstyles: DSE801, BE112, and Joye302; but not with the M201. Their "LIMITED TIME OFFER" and "Super Sale" prices are pretty good. Interestingly, they don't specify that an
atomizer is included in their starter kit. Batteries, cartridges, and charger, yes; but no atomizer? [Probably an oversight on their website, but I won't
assume again.

As for a parts guide for "dummies" (
your word
, not mine), the closest I've seen is
VapeAtron's Model Guide. There are some errors in there, but some of them come from the manufacturers' own websites, so we can't blame VapeAtron.
Have fun straightening all this out. And keep asking questions! That's how we all have learned what's what: from each other.
