Wismec 3 Battery? No good. Breaks within a year without dropping. Replicated on two mods.
Wismec 2/3 mod? Yet again, poor manufacturing. Wires not soldered properly. Almost lasted a year.
Squid Industries Double-Barrel? Craps out after 1 month without any damage. Wont turn on.
GeekVape Aegis Legend? 2 months and not reading the batteries right. Never so much as tipped over on my desk.
SMOK? Had more than I can count or bother to recall the exact models, but every one busted within a year.
None of them seem true to their warranties either. They make it as tedious a process as possible. I haven't tried with the Aegis Legend yet, but I'm going to go out on a limb here and say it's probably more of the same.
At this point, I am convinced that I have spent more money on mods than I have on juice. These mods are all made like crap. I don't want to spend $80 every few months to get a new mod. I just want to vape for gods sake.
Has anyone had a mod that has lasted them over a year? What kind was it? I've asked this before and that's what led me to the Double-Barrel and the Aegis Legend. Both have failed on me even sooner than my previous attempts.
Therefore in summary, there are plenty of good mods on the market that have the capacity to last in excess of a year.
The issue your facing, apparently is that you want to walk around carrying a battery pack, instead of a mod and there were fewer of those made so less choice.
In the 2 battery realm, there is plenty. I have a Topside dual that lasted me a full year of daily use before I lost the stupid thing... still upset I lost it.
Figure I'll find it now that I've replaced it with a new one... lol.
I have a 2 battery Uwell Crown mod that I've had set up a year, but I don't give it as much love as I do the topside... plus the bottom is more rounded so it topples over at the slightest bump. But despite falling over on a regular basis it manages to be like a Timex, takes a licking and keeps on ticking.
I've had far more positive experiences than negative. I've had one mod break and one mod that was DOA, but that was it. Even my son's Wismec I purchased for him on clearance for 20 dollars lasted him 3 years of daily use before the screen went, but even it still vapes, you just can't see the screen...
While my son's wismec might be luck, it's not all luck..
Mainly it's a matter of paying attention to the experiences of others, and buying on sales so even if I don't particularly care for a mod I won't feel I'm out much...
Sales are cool... I bought 2 Jackaroo kits for under 20 each, 2 Asmodus Colossals for about 15 each, etc etc etc. While sales like that might go the way of the dinosaur due to regulations, for the last couple years you've not needed to spend 80 dollars for a mod either with few exceptions.
