i don't suggest you get the 601 e-pipe, I purchased 2 from eastmall when i first started vaping and they both died in a matter of hours, I also never got any resolution from eastmall, but thats a different story. Basically the issue with the DSE-601s is that they aren't sealed properly around the atomizer, so when liquid pools in there, it goes directly to the battery area, the circuit board, and of course the automatic switch. Honestly I recommend a mod, I personally advise the V3 since its small but packs a large punch (larger than any e-pipe would) and it looks great. Either that or a silver bullet depending on his size preference. I also recommend getting mega cartomizers as they will drastically reduce your maintenance and refills. What will draw your husband away is a faulty or difficult device, and in the end if he doesn't like it, the V3 is very female friendly (slender, small and elegant for a 6v mod), the SB is large, but I've seen women carry it in their purse just fine.
