I held off a couple weeks after buying my two 5 packs of these before saying anything, but my first impressions the day I bought them were below dismal.
Why I ordered them: I figured I get blue tubes for my CE2s and a couple free drip tips out of the deal if they suck. Unfortunately, the tubes in these have a section that's part of the molding, and cannot be removed and used in CE2s.
What I ordered:
1 5 pack of the 2.4/2.6 ohm
1 5 pack of the 2.8 ohm
2.4/2.6 all meter at 2.8 and higher.
2.8s all meter at 3.0 and higher.
Flavor: Muted compared to CE2s
Vapor: Muted compared to CE2s
Throat hit: Too harsh, it's an irritating throat hit, not a good throat hit
High voltage: 8 watts burns. 6 watts burns. Anything above 4 watts and 50/50 liquid can't wick fast enough. Even at true 3.7 volts with one that metered 2.9 ohms I'd hit dry spots constantly. At 3.2 volts (eGo and eGo clone batts when under load) they're a terrible vape.
Major gripe: They need a mouth piece with that little rubber plug built into it. "But the tweezers they come with suck, get better tweezers and you won't have a problem!"
I call bs on that. I have a great set of tweezers, but these things go flying off if I squeeze too hard and just flip around if I don't squeeze hard enough. That's not a big deal to me, honestly, I'd deal with it if the product didn't suck.
Biggest gripe: The time I spend replacing the plug on them I usually lose a good amount of juice running out the bottom. I just tried to refill one (that is now in the trash) and by the time I finally got the rubber seal back in, it drained half it's juice out the bottom onto my table. I pulled the seal, refilled, and all the time I spent fiddling with the seal, the entire carto drained out until it was empty.
I'll be trying to cut out the inner crap on them to make the tubes usable on CE2s. I like the blue color more than the smoky CE2s I have.
Notes: For high voltage, I disassembled one and tried to make the wick opening the tiniest bit bigger. Obviously a huge mistake. Within 5 seconds after filling, before I even set down the syringe, the liquid had run half out the bottom, but the time I grabbed a tissue it was empty.
These are garbage. Complete and utter garbage. So are the G4/G5/Vortex/Vortex 2.0 for that matter.
I'm very angry I've wasted so much money on unvapable cartos, between these and the G4/G5/Vortex/Vortex 2.0s. At least the Vortexes were somewhat vapable, but their vapor production was terrible and the mouth pieces sucked and lead to pockets full of juice.
At least with the Boges and the eGo-T I was able to use the crap til it was dead to get my money's worth out of it. (Not that Boges and eGo-T are bad, but the CE2s are worlds ahead imho)
Take it for what it's worth, I've tried an awful lot of cartos and carts for 510 atties (smart carts, smart carts 2.0, blue foam modded carts, lucid carts, etc etc etc) and nothing's been better than the CE2s for me.
I used to syringe mod all my CE2s, but now with the new tubes I don't have to bother. I still have to either remove or cut into the inner fill cup to make them wick well for me, but that's only a one time deal. I can reuse seals on dead ones on new ones without a problem.
