When I decided to expand from my ego collection and get a battery changeable 
mod I did a lot of shopping, looking and studying and one day decided Bottom Feeding was the way for me to go.   More shopping and waiting for them to become available, I ended up with a custom one that I still have, still adore,  and use from time to time.   Then I expanded my collection with a few models.  
 
I acquired a vmod1 on a July 4th sale in 2011 and now have both the vmod2 and the XL.   I like the ergonomic design and find them fabulous for my purse and for travel.   IMHO there is no better pocket mod, period.  And, I've tried a bunch.  
I don't use feeders as much as I did, but they are still a useful part of my arsenal.  In fact, I enjoyed my little vmod2 very much just today.  

 My feeders will always be a bit special to me.
