My destroyer dna 12 arrived a couple of hours ago and I'm really lovin it. I have a efest 18650 IMR 2000mah button top in it and it fits just perfect. I also tried an AW 18650 IMR 2000mah in it and it also fits great. I'm really lovin this destroyer. Mine has the pistol grip and is made of all African wood. I'm just so thrilled to own this work of art (thanks Cappy you did good). I don't vape at high wattage usually in the 8 watt range. I have a 2.1 ohm Penelope in it and I'm in seventh heaven (really). So I set the Destroyer to it's center potentiometer setting (~8 watts) and bam nirvana but just a little too much, so I'm vaping it right now at around 7W. I love how easy, using the thumb pot, it is to adjust to taste. The size of it is around 1/2 to 1 inch smaller than my VV Destroyer II. It's very comfortable and the convenience of using just one battery is awsome as well. I have to give this APV two thumbs up. If I had 4 thumbs I would definetely give it a 4 thumbs up lol. I am so happy I pre-ordered this wonderful mod. This is my 5th RMS mod and although I love all of them this I can see will be my favorite. Thanks Cappy you do excellent work and I couldn't be happier! Got to go now because it's hard for me to vape on my new VW Destroyer while typing.
