I already have an MVP - version 1. I just am looking for a VV mod with replaceable batts so I don't have to be caught with my vape down once the MVP wears out.
The more I look, the more I'm liking the SID.
I guess I'm misunderstanding your reasoning. The MVP has one of the longest lasting batteries available. Are you saying you want a mod with replaceable batteries so that you can replace the batteries when they wear out and stop holding a charge? And you expect that in a sub $50 mod?
Please tell me where to get such a mythical creature. The components in sub $100.00 mods are not designed to last 24/7/365.
If you do only 300 puffs a day, the fire button alone is subjected to over 100,000 presses in a year. That's what I love about the MVP. When the battery dies, then I replace the whole mod because I am not under any false pretense that the materials used are designed to last longer than the battery.
If you are serious about getting a mod that "outlasts" the batteries, you need to stop looking at the $50.00 level and start looking higher. There's a reason most $50.00 mods have a 30 day warranty at best.
You will need to go with a ProVari, Semovar, ZNA, Protovapor, or similar device that is constructed from materials that are designed to last years not months. For example the button on the ProVari has a minimum rating of 5,000,000 presses. This equates to about 45 years of use. The Protovapor and ZNA use similar high quality materials in their builds. Anyone can put something in a stainless steel tube and make it look "tough", but if you have a cheap dime store fire button, or crappy 510 threads, then what good is it?
Now if you are going for a SID or Vamo because you like their looks, or you like the fact that you can have a stable of fully charged batteries to swap out with in case you "forgot" to charge your MVP. Then maybe I'd understand.
But you are chasing unicorns and leprechauns if you expect a $50.00 mod to last the day to day rigors of use for longer than the 1st set of batteries you buy for it.
