The F16 Kit is brought to us by Foger. The creators of this piece of hardware clearly know what they are doing because this vape pen has been around for a while, and it is clearly not going anywhere. It has a sleek design, which makes it comfortable to place in your pocket and be on the move. It has a built-in battery that has a capacity of 1100mAh. This amount is will certainly be enough because it can potentially last you all day long without having you looking for an outlet somewhere. The tank capacity is a good 1.8ml; giving you the room you need to appreciate your vape juices. The stainless steel construction does not only give it a sharp look but a durable built as well.
