Lisa,
SO glad you got yours.... IT is tiny isn't it? I have found many different ways of activating this thing. The one I like the most is using my middle finger knuckle to push the button while holding the Slim with my forefinger and thumb. But it can also be used in so many different positions and even stealth vaped with it in your palm using the tip of your pinky to push the button. I also was not too keen on the bottom button after using the SD for a little while but this one is so easy to push and so comfortable.
Over all I give this little Pocket PV a 10 in form and function. Plus the convenience of the carto makes it a great on the go
device.
