Ordered the nano kit and K-Pico from Cloud 9 last week, looking forward to trying it out. I've also been watching the Erl crowd with interest. But, may wait until the P3 comes out before I invest in another topper.
I don't know why it won't work, but they specifically say the K-Pico won't work with the K-Nano, both of which are made by mod Factory...
Like I said, mine works beautifully with a nano ring from a generic aftermarket set...no clue where or when I got it...hahaha
So, if you get those in, and it DOES work with the K-Nano/Pico set up, please let me know...I'll be highly disappointed!
