I'm waiting on my iStick 50w in the mail right now. I ordered from MyVaporStore as well since everyone raved about their shipping time. I ordered Sunday (4/26) and the estimated delivery is this Friday (5/1), so it's much better than I'm used to, seeing as how I normally use FastTech (lol, right?). I managed to grab it for $50.27 after shipping. For anyone who might be curious, that 5 day shipping time is from their office in NY to southern Alabama. I was using an MVP 2.0 and liked it a lot, but one too many drops and the base of my Nautilus wouldn't thread onto it, so I tried and tried but could not get anything threading into that 510. I began using my Nautilus (with new base hardware from evape.us - awesome transaction by the way) with my Stingray mechanical. For one thing, I am beyond sick with changing batteries. My mech was used for .2+ ohm builds on my Tobh, but I HATE the way mechs operate with prebuilts. They work as intended, but once the voltage drops below 4.1, it hits like a toy truck around 8-9 watts and I'm having to hit it for 10 seconds+ to get satisfactory vapor.
I'm really hoping this iStick solves all of my current issues (no battery swapping numerous times per day and being able to vape with consistent results). I went with the pack and bought it on blind faith based on comments in ECF and Reddit. I will post a reply with my thoughts once I receive it and have some time to put it to use.
