It is easy to use and simple to set up and put together. You take it out of the box and put screw it together. Put your juice in before you put your batteries in since the coil does get hot and then test it to see if the SMOK comes up on screen if it does then you are good to go!
You can have different modes set to your liking with your flavors and what is in them. It comes with extra parts like spare gaskets and spare coil. The screen is 1.9 touch screen that is HD. It allows you to change the background and colors to your liking.
It also has an input keyboard for your passcode. It does not over heat and it is best puffed at 25W because any lower it will not give you the nice size smoke cloud.
The beauty of this is that you can change out and basically mod the vape to your liking meaning you can get a bigger tank and mouth piece. It does have certain coils and batteries it has to take but other than that it is fine and it is best to get extras since coils tend to burn out after so many uses. It is also tiny and not really to bulky. It is about the size of a cell phone or even smaller but is thick. The firing time is 0.001s and if you are not careful it could be to much if the wattage is high.
There is a silicone ring that comes with it and it goes over the tank just incase you drop it so I highly recommend. You can also get a case for it to give it a little more support and I found it on amazon.
