This was much first vape unit that I researched first, and felt that would be a good choice for myself personally. BIG shout out to the folks at VapeMeet for their help with all of my noob vaping questions. Fast shipping too!
First I should mention how others say it leaks - NOT one little bit has it leaked for myself after almost a week of good usage 300 puffs on the counter. I'm using the RPM pod, and RPM 0.4Ohm mesh coil.
Battery life seems great! DO NOT charge this with anything higher than 1.0 amps, you'll run into issues. That means all of your newer model cell phone chargers. I used my Dell XPS laptops USB port that has USB 3.1 generation 1. Its output is 900mA, perfect.
Build quality seems very nice, with good materials used. The pod is not going anywhere as it has a nice tension fit. Feels solid in the hands due to its weight.
The display is really nice! Changing the colors to what I like whenever is cool, and the visibility in bright conditions is good.
I'd highly recommend the Smok RPM 40!
