My pleasure!
First of all, I received mine yesterday. I only became aware of the Hana Modz v3 last week and found my way into the thread about SSVapes. I started sending email messages to vendors asking when they might have them in stock. (I think this was Wednesday). Following 4 email messages and maybe 3 hours I got a message from a vendor that he had a few on hand and I could buy one of those. I asked if I could inform others in the forum that he had some and he asked me not to because they were getting a larger shipment this week. I'm glad he was right.
After one day, my first impression is very favorable. Fit and finish of the device is great. All the edges are smooth. I've seen a couple of complaints on youtube, but I have none of these problems. The battery fits perfectly and does not rattle. If you sit the device on a solid surface with the correct battery installed (I'm using a Sony VTC4), the LED display doesn't go out. The battery doesn't rattle.
The only issue that I've seen is one mentioned by riptripper, and that's the stain. When I first removed the device from the package there was a stain near the 510 connector. I dipped a q-tip in alcohol and wiped the stain away. That's it! I've tried all the known button combinations -- LED right, LED left, lock device, lock wattage, normal mode, stealth mode, wattage up, wattage down and everything works as designed.
So far I've used the KFL+ and the IBtanked 22mm cartomizer on it, and both have worked flawlessly.
All in all, a great device that I'm very happy with. Would I have liked to paid less for it -- absolutely! Based on what I've paid for other mods, is it worth $250? I think so. I have absolutely no regrets about this purchase and it's already my favorite among the 6 mods I own.
I was actually going to make a thread just like this, thanks!
