Finally got my 2.5's and 3.0's today (thanks for trying to get them to me by this past Sat), of course USPS sucks & COV rocks!
My thoughts, the differences I see comparing them to the last version (2.5) I received just a couple weeks ago:
1. It appears the coil is not wrapped as tight around the wick as the previous version release. Seems to work much better this way. Also looks as though it wicks a lot better than previous versions.
2. From what I saw earlier today the coils seem to heat up a lot faster (both 2.5 & 3.0), glows bright really quick.
3. I did a dry burn initially, nothing on the coil to burn off, so, No Bad Taste.
4. Included in the box is 5 tiny little pieces of filter looking stuff (which if needed, defeat the purpose of no filler) No instructions on what to do with them.
5. Only 1 DUD in the box of 5 - it will fire on nothing (I've tried just regular 510's, regular 901's, GG's, Chucks, Prodigy, Protege etc.... that one will not fire at all.
All in all, so far, I am very satisfied. I will wait to see what the coil looks like after the next refill. The earlier versions I have really "cruded up" very quickly. I am hoping the coil not being squeezing the bejee's out of the wick that it will help with that buildup. The juice I use is fairly dark, so, it may be something I'll just have to deal with.
