My Evic AIO just came in today so I'll have to check it out before I can comment on it. If I were buying a first stand alone mod again I'd go after the Evic Mini 75w. I now own 6 of them and like them a lot simply because they are a nice size & weight, nice display, have all the normal modes including TC with SS (not that I've ever bothered with TC, like DJS I simply stay in power mode), a separate battery, and none of them have caused me any traoble at all. And that is about all that distinguishes most of the mods on the market. In other words they all work about the same. Some don't support SS in TC but those tend to be the earlier ones. Now some have programmable functions in them, but for me I don't see the point. Some are DNA based chips that are supposed to be better, better at what I don't know, other than having a higher price.
Another cute little mod is the Aster. I have 2 of them and the only complaint I have with them is they don't stand up well as their base is a bit small and tip over easily. But they are small, have everything that an Evic Mini has, and have a small price.
