Yeah, I think I should stay away from that then!
Need something that she can toss in her bag.. that's another reason I'm a bit worried about the glass on the protank mini... but it is Pyrex!
I like the look of Todd's setup he's using with the protank mini - Kanger Mini Protank Kit - YouTube - that size battery and protank mini might not be too bad, I could convince her to use it I think. She also would't have to carry juice around when we go out!
They do make them using Pyrex!
