I also just received my stainless T-tips and have been using them on my eGo. These are fabulous!!!! They look and feel like they were designed for the eGo. Perfect fit, perfect look. These make dripping so much easier. I also wasn't expecting it, but I do taste the juice a little better. I don't know if it's because of the open end or what...but this is wonderful. That's it, I'm only dripping from now on. (except in the car)
For the car: I did find "510 cartomizers" at nhaler that I really like for driving. These are foam wrapped and are just like a regular cigarette filter (soft). These (kr808b) are smaller than regular 808 cartomizers (kr808d), but much easier to deal with. They hold about .3 ml and are refillable - Okay for driving purposes and I just carry a handful to keep in the car and change them out as needed. No adapters needed, they screw into a 510 (of course eGo). Best of all to me, they vape like my wonderful 510 eGo should vape. I much prefer the vape of a 510 over a kr808 (smoother and mellower).
Just my 2 cents but I'm thrilled with my T-tips and 510 cartomizers. I vape anywhere and everywhere happily now!
