Was able to put mine through its paces today after receiving it Friday. I'm a big fan of the Goblin Mini, so decided to rebuild one with 28ga Kanthal to increase the resistance. This proved futile, as it simply reminded me that as much as I love the Mini, I hate the screws as I snapped through the leads of three coils.
Figured I might as well have a little fun, so I built it with 26ga. Dual coil, 0.5 ohms, vaping at 33 watts on Standard got me through almost a full tank before the low battery warning started appearing. Turning it down to 25 watts let me finish it with ease.
For a mod that I would use when going out to dinner with the wife or an event where I know I won't be chain vaping, this thing is perfect. It'll be great for those times when I need to dress up a bit and don't want some brick or tube showing in my pants, shirt, or jacket pockets.
I typically run my Minis at lower voltages, and the 33 watts I set was higher than normal for me. I'll have no problem setting this up for better battery life and longer vape time on one fill. For the price, size, ease of use, and versatility, this thing is a no-brainer. The auto shut off can get annoying, but I've got other mods with it and it's not a deal breaker for me.
