Since it's my first vape pod, I don't have anything to compare it to. I went with the Devil Red one, and so far it's been working great.
It's easy to use and small enough to take with you if you wanted. It can easily fit in your pockets.
I did have a leakage problem the first time I used it, but that may have been my mistake. When filling the cartridge, make sure the flap is completely closed to avoid leakage problems.
There isn't really anything to indicate how much juice or salt you should pour into the port, but I just fill it halfway to be on the safe side.
It comes with a spare coil and an extra set of directions, which you should read (pretty much goes without saying), so that's great.
Other than that, it's great. It's an easy, smooth vaping experience. Highly recommend.
