Small size form: eGo One,
istick Mini, Vision Spinner/other vv ego
batteries, eGrip
Best choices I would pick are a combo of eGo One and eGrip, best of both worlds. I have quite large hands and the eGrip hides completely inside my hand and produces great vapor. I was also surprised by the weight, but that isn't really an issue with me at least. If you have a chance to take your colleague to a vape
shop, do that and show her the eGrip and eGo One along with other options others have suggested, like the iTaste VV V4.
