Just got my Ivogo mini from Angelcigs today! I soaked it in some alcohol, soap, and hot water for a little bit, then gave it a quick rinse and wipe down with a microfiber cloth. It wasn't dirty by any means but I wanted to clean it anyways. First thoughts... very well made, I don't see any defects or scratchy threads. I put a 9 wrap 28 gauge kanthal coil on it using a 2.4mm screwdriver, came out to 1.6 ohms, and then put some rayon in it. Super super easy to build on! Even easier than the KFL in my opinion. The airflow adjustment seems to be working well, I loosened mine just a teeny bit to my liking, and top filled it with my finger over the air hole on the base. No leaking at all from mine. I gave it a few minutes for it to wick and I'm vaping on it now on my Hana mini. Loving it so far!! I see myself using this a lot. I highly recommend it!
