I am still trying to decide between the two. Each have their own respective negatives, but that just makes it harder to choose. The heat regulation for the BEC Pro is a bit concerning to me, but I probably won't go above ~30 watts more than once or twice(depending on what I decide put with it). However, hearing that the T5 has problems with people frying the chip is also worrisome. I do like the GUI on the T5 a lot more than the BEC for the simple fact that it shows more information and is easier to access, but once I find my happy spot I probably won't even bother adjusting the settings much until I decide to change something again. As far as battery life goes, I have stocked up on my VTC4-5's and it's easy enough for me to carry a couple of spare
batteries with me, which I probably won't even take this one out of the house, and just run one of my Mechs while I'm out and about.The size of the two is really interesting, but not really a deciding factor for me. The Boost feature of the T5 does seem like a really cool idea, and definitely something to make me consider it more. I've watched
reviews for both of these devices and while I am a fan of PBusardo and value his knowledge input, it isn't the say all and be all.
Honestly, after typing all of this out and looking over all the information I have accumulated over the past few days, I think I am leaning towards the T5. While it is bigger, it does have better safety with heat regulation, since I have a habit of mindlessly chain
vaping. And I do like some of the extra features it has going for it.
