So before i got my REO i was pretty much only vaping my then favorite setup provari + 306dca. Loved the DCA and the 306 attys. So when i got my REO i luckily had a 306 drip tip because i sure as hell didnt want to go back to using 510 attys after using the 306 for so long. ( Not that i hate 510 but i like 306 alot better). So for the last week i have been using my REO only and really dont see a reason for now to go back to my other setup, the REO is perfect in every way and holds a 6ml bottle of juice and a bigger battery. Only thing it lacks from the provari is VV but it works just fine with all my juices using a 1.5-2.0ohm atomizer. The first problem i noticed when using my 306 drip tip was that i got juice in my mouth all the time. No biggie but i would rather not have hot juice splattering inside my mouth when vaping! So i searched the internet and the forums and really couldnt find anything on a really long 306 drip tip. So this is what i came up with and it works great. I happened to have the Twitter special DCA setup with 3 different top pieces to fit all different 306 atomizers and not just the MA306. I found the one that fits super tight and just popped it on the atomizer with my ming drip tip and i got over a half inch extension! no more juice splattering and i get to use my 306, favorite drip tip, and DCA! well half of the DCA.
