That one has separate cartridges for each type of input so no risk of blocking your liquid cartridge. Having said that some online reviews suggest it's not the best e cig on the market but it's a good compromise for a portable dual use device. I may well buy a separate e cig yet, given what I'll be saving on smokes it won't be hard to justify the cost - hard to judge how much e juice I've gone through since yesterday but I'd say well south of $1
Google will give you plenty of device options although the "medicated" juice isn't as widely available.
