I'm just started vaping a month ago and after the first week with my Volt I knew the standard carto's were NOT the way to go. I mean, I hated not knowing what was left in a carto. A newly opened vapor shop in my small town sold me a clearo's for $8.00. We would not tell me where he got them from or what brand they were but it done a great job for the first three days before it started leaking something awful and juice coming up to the tip.
I'm so glad I found ECF! Instead of buying another $8.00 clearo I found the Kanger M3's for $2.50 each! A bought 8 of them and rotaing five different flavors. I still don't know what the guy at the vapor shop is selling, but it is not the kanger M3. Out of the five I'm using, only one gives me a little draw problem now and then. To me I just like how the clearo's vape and taste when compared to a carto and knowing how much juice is left when compared to the carto's as well.
I just got me an eGo C Twist this week and really enjoying the Kanger T3. I also got the adaptor to use the M3 on the Twist. The M3 on the Twist works pretty well, as long as I don't go over 4 Volts. On 4.2V and over you can really hear the atomizer cooking the juice and I get a gurgling feel when I draw.
I'm still a newbie with this, but I don't see a better fit for the Volt then the Kanger M3. But just juicing 80pg/20vg for now, this ratio may change in the future as well.
