I used to own an SVD1 a long time ago, it was nice an unique.
Since then i haven't seen Innokin make anything interesting or ahead of it's time, in fact quite the opposite.
The SVD2 is nothing to write home about.
By the time everyone switched to either DNA40 or to more powerful box mods, Innokin decided to make their flagship box mod 30W.
Yes it's built like a tank but I don't expect my mods to last 10 years since they become obsolete relatively fast, but the MPV was obsolete since before it was made and it's still more expensive then the superior competition.
Innokin was one of the last Chinese manufacturers to get into the sub ohm tank war, they had all the time in the world to design a superior tank, but still they managed to make the worst one of them all, with poorly designed heads that don't keep up and polycarbonate body (PC body seriously!?)
It's like they didn't want to be bothered with making a good one so they made a cheep (ass) one instead.
There are no stupid batteries, just stupid people.
Innokin's cig-a-like from wayyyy back when was one of.. the 1st things I used nearly 4 yrs ago. Personally, have never had any issue with their products & have used most of them by now. I only think quality & reliability when thinking of that brand. In fact, my original MVP, MVP2, iTaste-VV3 & that AIO cig a like.. all still charge AND work, as well as they did on day 1. Their iClear16 & 30s used to be some of my favorite tanks at the time & regardless of the liquid in 'em (sometimes for weeks & weeks before needing to change a coil) could have any/every type of liquid in them & to date, never had any crack or fogging in 1 of them from that. So idk what special magic polycarb. they use, but it's been rock solid. As for the iSub.. it's been a great one too, plastic & all. Besides, for those who aren't into that or are afraid, that's ok too... Innokin also has the iSub-G (pyrex) for that very reason. I've had no issues with their original one as far as keeping up tho. Not at all. Thing is tho, imho.. it, & the subtank series clearos (anything with the smaller circle style juice ports in the coil, seems to work better using 50/ 50 eliquids... while those with bigger rectangular ports, i.e., SMOK VCT-pro, HORIZON Arctic, etc.. perform way better when using the highest VG liquid possible; 50/50 or less vg, can tend to cause flooding, spitting & getting e-liquid coming up the airflow path quite quickly) That being said, Innokin, imho has always been known to put out quality & for the most part, well thought out products. Personally, I'd much rather have that, perhaps a little late to the party..... than to waste money possibly... being the research & development team for someone else who is willing to release whatever whether ready or not.. knowing we'll all run to buy it... As they put out version 1, mini, 2, mini, 2.5 (same as 2 but remov d/t) 3, mini, unitank, Uni-mini, Aero, mini, aero V2, mini, giant, turbo PLUS Genitank in all those configurations too.... Aero MOW. MOW mega (aka: color options of Aerotank) & finally.. Subtank. Even then.. original.. now plus. Rather than putting out the mini as the original & waiting to finish developing the 25mm to release as the plus. Think of the millions they made doing that... knowing the millions we'd spend.. probably twice! =/ Maybe Innokin just waited until (they thought) they had it right... before release theirs as a finished product with 1 or 2 options... idk. As far as batteries tho.......... at the time of your post, I'm sure you hadn't yet seen the MVP3-PRO. Even as a 4 yr vaper tho & even if I have & tend to shuffle through a variety of gear throughout the day........ I know I'll be getting one of those to use as well. Can't wait.. So, just wanted to share that their iSub tank really is quality, despite being plastic.. & does work well too, keeping VG in mind.... it's more affordable too. Maybe try again using a lower vg liquid... or pass it on to someone who would. Their MVP-3-pro will go up to 60w, firing as low as 0.2 ohms. =) LIVE LONG(er) & VAPE ON!
