Used to use my Vamo with my AGAT2 all day everyday for about 2 months before I dropped it and destroyed the threading on the 510 conncetion of the Vamo. Been using my K101 with either my AGAT2 .9ohm or my IGO-W .5ohm steadily for the past 3 months. Have the Fasttech Nemesis Clone, Brass M16 clone, and trident clone in route. I've been extremely happy with my k101, just wanted a different look and for about $60 shipped, couldn't pass up the on the clones. Its been an interesting journey going from a disposable blucig - V2 - Ego - Vamo - K101 in about 7 months and now DIY liquids (which the batches I have made blow any premixed including high dollar premiums out of the water and at about $2 per 30ml much nicer on the wallet)
