So I just recently purchased the Kanger Nebox. I was pretty excited to get it because I've heard nothing but good reviews about it. One of the things that I really love about it is the size of it. It's very convenient to carry with you anywhere you go which is awesome! The switch from temperature control mode is very easy to manage which I love as well. I think that my only gripe with it is just the tank design. I noticed that just depending on the angle you set it down at, your ejuice an leak out of the device. The second thing that I didn't like was the compartments for the battery. The screw in part is kind of troublesome seeing as how you have push the battery all the way in and then screw the lid on. As far as smoke production goes, it's not my Turbo RDA but it produces a decent amount of vape. You can really taste the flavor of whatever juice you place into the tank as well. Overall, it's great on the go device, I would make it my daily vape. Kanger has always been a favorite brand of mine so I'm really liking where they are going as far as mods go.
