Portertown has it exactly right- the yihi sx mini is a great mod and deserving of all the praise it has received. yihi makes a great board/chip and the device itself is well-built and durable. it really comes down to the subjective stuff like looks, color, size, etc. but you can't go wrong with the sx mini.... i too have an ipv4 in pre-order. it also has a yihi temp control board in it so the vaping should be just fine. i like the way the cover slides off and on for a quick change of batteries specially if you don't want to wait for the on-board usb charger to finish. i much prefer to swap out batteries and charge them on a good home charger. again with the ipv4 it comes down to the subjective stuff but if it pleases you that way it should be a nice mod to have. just because a mod can put out 100 watts or more doesn't mean you have to vape it that way- you can put any topper you want on it but it is nice to know it can vape with power if/when you need it.
i think with either or both of these mods you will be set and satisfied for a long time regardless of what pops up in the marketplace. i know getting the sx mini has stopped my endless hunt for the next "best" thing and save me a small fortune. definitely worth your time and effort to explore these two mods for purchase IMHO......
