Interesting, I've emailed them a couple times over the past 2 weeks and haven't gotten any response either. Glad I didn't place an order with them!
Bump...
Anyone has the answer?
Here's what I found...
The 201 mouth piece has a slightly larger circumference than the 801. The cart of the 201 is slightly shorter in height than the 801 cart. If you try using the mouthpiece of the 801 on the 201 atty, it's loose. In fact, it's too loose to use because I could envision someone sucking the mouthpiece into the mouth and possibly down the throat.
I can't seem to separate the 201 cart from the 201 mouth piece like we can on the 801.
An interesting caveat, though. The 201 mouthpiece fits VERY tight in the 801 atty. Keep this in mind for that overly tightened atty that occasionally gets stuck in the JS. In effect, the 201 mouthpiece becomes an 801 atty removal tool. =)
Spot onIN fact the 201 carts I got with my 201 attys are actually a little too loose for me so I haven't had the best experience with the 201 so far. But I really like the 201 carts on the 801.
No electronic device is waterproof. Liquid coming out of the front of the Stick can only mean you are flooding it with liquid...

These instructions work for my V2
