I have been
vaping one for two days now. It is a very nice looking PV and the
vape is very decent. Will not leak or collect condensate like the Oval Elipse that I have a lot of experience with. The Elips was a great concept and a beautiful package but was not very robust or economical as far as consumables.
The economics of the Sole are very good even though the unit is custom. The economics of the Elips was very poor because of the atomiser and other issues. If you are interested I will post my Elips experience at length if you wish but for $20 you should just try it. By a couple of cleartomisers too for other juices.
You can also
vape while charging like the Elips but you need a Elips charging cord not the adapter that is supplied.
