The good:
Saved myself a fortune over the last six months, was previously spending around a £100 a month on cigars!
Coughs and colds clear up in a matter of days instead of becoming chest infections and dragging on (not sure if I can credit vype with this one, but have been so much healthier this winter).
Done of a lot of foreign travel over the last few months, and an e-cig in your room is much preferable to being stood outside your hotel looking like a naughty schoolkid.
Service from vype is great, orders turn up on time.
Customer service is faultless, whether email or phone.
The bad:
Had a few niggles with the e-stick, seal between battery and tips seems to wear out, ended up using the little sticker to wrap round the join. Have now switched to the e-pen, less nicotine so maybe not such a bad thing.
The ugly:
Nothing I can think above apart from still being a slave to nicotine
