I'm a novice, so take what I say knowing that. I can't tell you much about the one you've found, but I can tell you what I found.
I was looking into e-pipes before I went for a smaller battery for portability. The average US
ecig personality will direct you the Jazz Cartopipe, but if you're looking to replace someone's traditional pipe, I would think an automatic battery best. I don't think epipemods.com does that, but I never asked them.
AZsmokefree.com has two, the better of the two (it seems) is reviewed on YouTube. The one that looked coolest to me was
Liberro's pipe. They're a british company, so shipping can be rough to the US, but reviewers like Scott (igetcha69 on YouTube) were very positive about it.
