This is perfect for beginners. It's got everything u need to just fill it up & start vaping. It knows exactly what wattage setting to go to for whatever size pod u choose to put into it. No guessing, just drop the pod in & it automatically sets the wattage for u. (& keeps u safe by only allowing u to use certain wattages with certain pods. For example, I use a 1.2ohm pod &, when I insert it, it automatically goes to 10watts. I can change that, but only up to 12 watts for that size coil & then the device says "max power" so u're not using inappropriate wattage settings for whatever coil u're using. It's smart like that, Lol.) It hasn't leaked at all & it even keeps track of your puff count too... & the puff count doesn't reset back to zero everytime u turn the device off, (like another device I've seen) which is really nice. The airflow control slide on the side is perfect & gives u as super tight or as loose & airy of a draw as u like. (I'm a true MTL vapor, after just quitting cigarettes 4 months ago, so I like a very tight draw & u can get exactly that with this device.) Also, I got this over a week ago & I'd say I've used it a moderate amount, & still haven't had to charge the battery yet, so battery life seems to be excellent. It's a really nice device for ppl who want it as easy as it can be. I'm ready for a device with options to change coils now, (only bc it's cheaper than replacing the entire pod everytime your coil needs to be replaced) but this is very nice if u…
