I think you'll like it, it really gives you a lot of flexibility for builds. I really like mine, have had no issues, worked great from the get go.
Its my favorite tank so far, very solid performance. I've owned the aromamizer 6ml, the Mt rta, mutank, tfv4 and now the Griffin and by far the Griffin is my favorite out of all of them.
The deck is super easy to build on, you don't have to stuff it full of cotton to keep it from leaking (Mt rta/mutank). Close the airflow and juice flow control and no leaks at all when filling. The top fill holes are huge (Mt rta) I'm sure you could easily fill it with a dropper bottle, I use unicorn bottles a with no trouble. The airflow is great, the included delrin drip tip seems just right bore size and it has the adapter to use your own 510 drip tip if you want. You can access the deck without draining the tank (Mt rta) which is nice.
Overall it's a very good rta and I have absolutely 0 complaints about it. As always I'm sure someone won't agree with something I said above but for me it's hands down the best rta I've used and it's not expensive at all. I paid $40 for it at the local Vape shop, I could of gotten it for $35 shipped online and possibly even cheaper but I'm glad I got it in person and didn't have to wait for it.
I'll be buying another one some time in the near future for sure to have as a back up.
