I just received my Wetbox yesterday. I think a bottom fed mod is ideal for use with cartomizers as there is no leakage. Other than being unable to change flavors on a whim the
device is exceptional. The convenience of not having to top off every 6 hits makes up for it. It is really well built with a personal touch added by the manufacturer. She really pays attention to detail and it is much appreciated. I have the 510 version and have been using it with bigbuyer's (cloudsofvapor) high drain 14500's and it hits close to my Prodigy V2 5 volt with a 510 cartomizer. Being a high voltage guy myself, I am now awaiting some LR 510 cartos from Provape and see if they make up the difference. I know there is a way to use them with a LR 510 (by removing bridge) but I am content. All in all, it's a fantastic
device for the vaper with moderate experience.
Also, the pics on the cloudsofvapor site must be from prototypes. The paint on mine looks much much better than the ones in the photos.
