Converting my parents

Hi all,

After watching my wife and I convert to vaping almost 12 months ago, my parents (both mid 60s) are ready to bite the bullet and give it a go. So for this to work, the setup needs to be as simple as possible. Both are heavy smokers.

I've been using these for a lot of the time since I started; http://www.e-smokeireland.eu/product-p/megadcc.htm. I initially thought these would be a good option due to the fill once a day requirements, but I've images of my father overfilling it and then vaping to it literally starts to smoke.

Due to recent availability issues, I'm a convert to these; http://www.e-smokeireland.eu/product-p/vision.htm. I think my mother is a little wary of the smoke it or inject it look, but I guess we all were a little self conscious initially. To me these seem a little more fool proof as they can see whats in them, but perhaps somewhat more troublesome.

Has anybody been through a similiar situation, and what did they recommend.

BTW, the starting point will be 900/1000mah ego batteries (I haven't had a 650mah yet, any rough ideas on how long they last). I need to buy about six of these as I need some for myself. Anyone come across good prices lately.
