I'm going to say something I haven't said about a vaping device in years. The IPV V3-mini is shockingly good. I've got a lot of very good vaping hardware that I really like, but this is in a class of it's own in terms of flavor, ease of use, repeat-ability of vape, cleanliness, and size. I have other devices that hit some of the aforementioned, but this little guy is the whole package. Just shocking really.
I won't repeat what others have said regarding pros and cons since they pretty much nailed that and needs no repeating, but I do want to to discuss what I find most interesting with this innovative technology.
Pioneer 4U and YiHi have moved the bar, in a good way, for how to achieve a good reliable vape with 3 determining factors. 1) Pre-heat settings (P1 & P2), 2) Temp setting, 3) Liquid flow control.
Pre-Heat: The ramp time of coil heating is more critical that many realize. The ability to heat quickly with a higher power level not not only means we can vape quicker at our preferred settings, but it will reduce the caking of the coil giving longer service life, especially for WTAs, sugary juices, and custards. Since ADAs are supposedly non-rewickable (I have yet to determine that), good coil life brings cost of ownership down by a bunch.
Temp Control: Ever since temp control became a thing it's been voodoo to most vapers. Just too much knowledge and time to get a good, consistent vape. This is eliminated with this device and temp is only needed to dial in the warmth you prefer and the volume of vapor you want to produce. Nothing new here except no need to work at it or be knowledgeable to achieve this. This is a big step forward.
Liquid Flow Control: This is the true innovation on this device and what previous temp control mods have lacked. The ability to accurately control how much juice gets to the wick not only means a saturated vape with really good flavor, but also means the coils and wick will last a good amount of time.
Boiling down a really good, consistent vape to these 3 things a user needs to setup (and not have to fiddle with again) and have it be clean at the same time is revolutionary. This is what temp control should always have been like. Adding the juice flow control just put the last piece in the puzzle. With YiHis 2 new devices coming to market this might start a trend. Unfortunately YiHis modus operandi has always been to be very expensive to license their technology. They will be happy to sell other manufacturers chips, but it might be too expensive to be viable for 3rd party mod makers to want to design mods with it. I hope that isn't the case since that would really curtail widespread adoption of a really good technology.
I'm just shocked and really impressed that this all works so well.
