Oumier Vape has released a few good products in the past and when I saw the Wasp Nano V2 for less than R400 I figured I would give it a go. If you are looking for AIR and lots of it then this may be for you! I have closed the three airflow slots down to small holes to get my preferred airflow draw. A simple build and I popped in a BVC Framed Staple 0.39Ω. 2ml with normal glass and they don't say what the capacity is with the included bubble glass which I used. Top-fill works fine. I hate 810 drip tips and replaced the standard tip with a Drip Tip by Bill from Germany. Pretty good vape and a very reasonable price! Flavour is good! Not a bad buy at all!
