I just wanted to quickly post from my vaked daze to report on my experience with the v4 tops and the KISS globes.
First of all, the KISS globes.
These are great, believe all of what the others have told you! The new wicks are so super absorbent that they make me feel confident (and all of the other adjectives commonly used in a sanitary pad advertisement). Once you go black, you don't go back when it comes to ceramic wicks. I seem to be able to get more of my concentrate to absorb into the wick and get more clouds for longer than with my 3.7v ti gr2 kiss carts.
The glass is so helpful, being able to see the clouds really saves my lungs a lot of unnecessary over-inhaling - and saves me a bunch of concentrate that I didn't need to vaporize at that time!
The extra heater was a pleasant surprise too!
Now to the v4 top.
I have used the v1, v2, v3, hammer and now v4 tops. I have found with my v1 and then v2 tops that I have to screw the cart/herc on just right so that the centre post would connect properly. The v3 seems to have been a lot better in this regard, but the v4 is perfect. It seems to have a self adjusting centre pin on the v4 top which means you can screw the herc on that bit more firmly (in my case) rather than leave it what felt a little loose on the older tops.
The Persei main body has nigh on reached perfection at this point. I could only see it getting better by somehow getting smaller and still retaining the still functionality.
I cannot wait to try out the 8!
Now back to the mango bomb shatter
