I'm REALLY sorry that I haven't gotten back to post what I thought about these carts sooner!! 
I just received my eGo-T atty that I had ordered from you a couple of days earlier, and I was like a kid in a candy store with the both of them...
but as much as I loved the tank, it sadly did not last very long, and is a luxury I just simply cannot afford...
But these Smart Carts are another story... they allow you to have almost the same experience, only you can use them on any 510 atty. I found the little bit of filler to be just perfect, even with my thickest VG... the only thing I noticed was there is a little drop of glue holding it in, and when I tried to remove it the little plastic bridge inside came out with it. If anyone wants to replace it with the blue foam, this might be a problem...
A friend gave me some from another supplier to try, but the filler was a lot more dense and I had to remove some of it to get it to wick properly. I didn't notice any glue on those, but yours work much better as they are.
All in all, I just LOVE them!! They are like the poor girl's version of the tank to me...
LOL!!
Thanks again for the Gift Cert, and the opportunity to try something new!!
