I have been wanting to try out the new 510-T batteries since they are 340 mah. 1) Are they totally compatible with the regular 510 atty (and, therefore, the 306 atty and the adapters for the 510 batt)? 2) How is the 510-T atomizer? Figured I might just go ahead and check it out while I'm at it, just order the whole kit instead of just the batteries. One more toy to experiment with. But, I'm getting the feeling that the tanks may have some issues. Are they worth giving a try?
