Fits in my hand nicely. Difficult to fill for me perhaps not others. Will be more expensive since it's disposable. I like it because it's small.
The Halo Zero is very good. Good flow and lasts a long time.
My wife loves her two Zeros and the Pods.
Easy to fill, last long, these are my new favorite device.
The first pod was leaky, not impressed. The second pod worked good and changed my mind. Been vaping for a long time and I know sometimes things are hit and miss, hope all future pods are trouble free
