I have an eGo style battery w/pass through, and an Evod tank.
I'm happy with it.
It takes up next to no space, rather than a huge, clunky, (to me) awkward looking mod. I can throw it in my pocket or Random Stuff Holder in the center console of my car. The whole thing cost $30, I won't cry if it breaks or I lose it. And if I DO lose it or break it, I can walk into about any smoke shop and pick up the exact same gear.
Is it the best? Well, define best, I guess. For me, I think so. I can pick it up and vape. Maybe switch out a coil if I need to. I don't need to spend epochs fiddling with wires and wick material. I didn't do that with cigarettes, and I don't want to do it when I vape, either. Some people love the tinkering. I myself, don't. (FYI, I also tried rolling my own cigs for a while, and hated that too. Curious if the tinkerers were also rollers when they smoked) I wasn't always searching for the best lighter on the market, or the newest cigarette technology. Again, to me, that doesn't make sense to do when I vape. I do see the appeal of doing it, it just doesn't appeal to ME.
Everybody is saying "famous last words". I... really don't think so. I can't say no for sure, but I can't see what would make me upgrade. I also hear a lot of "You should at least get a VV". I HAD a VV. My first battery was a Twist, and I was wholly unimpressed. For one thing, it didn't seem to matter what voltage I vaped at. I didn't ever notice an appreciable difference in taste or amount of vapor, except if I turned it up past like 3.8, everything I vaped, burned. Yeah, that was money well spent on THAT battery. And then it disintegrated 3 months after I bought it. The ring that holds the power button just came off. The whole thing fell apart. It was never dropped or mistreated, either.
Sure, I could just think I "have it good" because I've never tried much else.
I get some "Oh... you're still using THAT??" like there's something wrong with me.
Is anyone else still using "basic" equipment and happy with it?
