I am going to the UK later this year and was thinking about picking up a screwdriver, however they are (comparatively speaking) quite expensive and there isnt a great deal of accessories for them like USB passthroughs and what would it be like getting spares through. So Stevens supply would be quite appealing.
Then there is the Janty stick (or Twisp stick here) looks like it has a few more accessories for it and a supply locally but all I see all there is on the Twisp site is spare batteries. Once again quite an expensive device.
Looking at some of the China suppliers websites they are starting to produce some of their own versions of the stick, so I am thinking of waiting until they get a bit more mainstream.
The thing is, I am currently maintaining stocks for about 3 e-cigs and I cant just settle on one, all have pro's and con's. For my next cig i'd like to buy a good all rounder so its one set of spares for everything.
I am thinking in the interim (to settle my curiosity) of getting a M201 or M401, but not sure which one would be the best to get.
I'd go for the M201. Here's why. The atty is the biggest- bigger than the janty stick atty which is bigger than the DSE801 atty. The DSE 801 and the M201 look identical in size and often colour, until you look inside the atty of the M201. The M201 has been my e-cig of choice and I use it the most because it offers more throat hit and vapour - but it's not perfect it's still auto and it's a liquid guzzler and I've been through 2 attys in 14 days (and awaiting spares) SO with the provisio you have enough spares then you will not look back with the M201 because it's a great all rounder for the heavy vaper who doesn't like towing around wires. You still need a screwdriver (with a manual switch) because that is the creme de la creme of the vaping experience. You haven't vaped unless you've tried a screwdriver type device. It's not practical for vaping in public because it looks like you are on fire But for home use it is Nirvana.
I agree that you need a few different devices for different situations. I downgraded my DSE 801 to standby duty status and use the m201 as daily duty until it goes to the service bay awaiting spares. The screwdriver (in my case janty) is for home off road use, it's the bundu basher of e-cigs at least for now. However if you are going to buy a prodigy won't you buy me one too. PM me if you are headed UK ways soon. I can't comment on Stephens device yet because I haven't tried it, but I would always buy proven hardware without a blink as we call them "the greats" on the main forums.
