Switchable Juicebox? Anyone ever tried it?

[want to quit]

So I came across this site that has the normal mods and this unit. Never heard of it and what do they mean by switchable juicebox? Does it mean you can put for example 2 bottles in their and just use the one that you desire?

3.7V/5V Switchable JuiceBox - 510 (2x14500) [juicebox510] - $53.99 : Zen Cart!, The Art of E-commerce

Oh and I never heard of them nor tried their juices but 5ml juice $2.69 pretty good price. Yet in some cases low price= bad juice.

oh ok gotcha. Was not going to buy it since it looks like a freaking water gun but was wondering what the switchable juicebox meant. Thanks for the input.
