I purchased one of the initial batches of the gray AirVape. It has been very good to excellent to use.
The only thing that kept it from 100 % excellent was the mouth piece design. With current upgrades and the magnetic approach is a game changer.
I love all of the cool comments I receive when using it. I've had mine many years it works great. A slight reduction in battery but as with ALL battery chemistries everything has a life.
You will be happy with this vape as with any vape regular cleaning is a must. Mine is used 2 or 3 times or more a day for years and it's still rocking.
