Happy owner of an iStick 60TC. If you have owned iSticks, this one is a step up in terms of overall quality and durability. I got the kit version with the Melo 2 tank and I'm glad I didn't wait for the vendor to get the mod only packages. Together they look, feel and vape great. The TC option really does extend battery life over the wattage mode. The flavor is better in TC mode and it generates respectable clouds in all modes. It feels great in the hand. The vaporizer can use Aspire coils, but I like the Eleaf coils. They are less expensive too. Eleaf is coming out with a rebuildable coil head The top fill feature is super easy. The buttons do not rattle - whoohoo! The side panels are rock solid - no looseness or moving around. You can use pass through charging, but I wouldn't. Eleaf will be selling side panels in different colors. So, you can customize the appearance. If you want a color they don't offer, you should be able to paint or use vinyl for even more options. The price is right. You should be able to find the mod alone for less than $30.00 and the kit with the Melo 2 for under $50.00.
Cons - the TC and +/- buttons are a bit too close together. But, once you have the TC dialed in, it doesn't matter too much. The USB charge port is on the bottom. Eleaf should have included a spare tank glass.
