I wasn't initially attracted to the mod TBH, kinda 50/50, after seeing the video I def think this will be a pass for me. The concerns I have with it are:
1) How good / efficient is the chip. After the Pulse 80 I'm kinda off any single cell mod that's not DNA and even then my next purchase will likely be a dual cell. Be interesting to see how battery life is. Nothing mentioned on the video at all about it, unless I missed it, but even the Pulse 80 was announced as having great battery life. Real life
reviews vary on that one.
2) There's 4 potential leak points on it: bottle to bottom feed tube, bottom feed tube to carrier tube, carrier tube to 510 feed tube, 510 feed tube to 510 assembly. Hmmmm. I'm sure it has been tested well, be interesting to see if there are problems though once the mods hit the market with widespread and protracted use. I'm guessing 6 months down the road will be time enough for issues to become identified, as it would with any mod. There will always be rogue units with problems, it's the nature of mass manufacture, what concerns me is more widespread problems over and above what might be considered the failure norm, such as happened with the Smoant Cylon and screen failures.
3) That non-replaceable 510 tube bothers me. Another thing to degrade.
4) Overly complex cleaning should you wish to clean out the whole system vs just the bottle, something I do regularly just to avoid gunking up. I like to keep gear clean and in good working order, not leaving it because cleaning is a bit of a hassle.
Certainly applaud the creativity on this but I think the USP of it, the top fill bottle, has been marketed by maybe making (for me, much) more of an issue out of current refill methods than what it
really is, especially if you choose devices carefully (and those devices don't have the multiple potential leak points). I've never cross threaded a Wotofo refill cap, I don't do it multiple times a day and Vandy Vape in particular do a real good job with their squonk bottles such that I don't get a mess of juice at all when I refill them. My tissue budget is negligible. The ease with which you can fill it for me though is more than countered at the other end with the complex cleaning and the potential for leakage and that small top tube to degrade.
I can see how it will appeal to folks with the 10ml bottle and the spare refill bottle (almost Vicious Ant style but without the carry cartridge) and even the design, it's a quite attractive mod, but nothing attracts me to use this over any other single cell mods I have. Indeed, even if I were in the market for another single cell squonk mod there'd likely be others I'd choose over this.
