Picked this one up after seeing VJ's post from 101vape. 18.99 for the Atomo mod with all 3 main battery tubes. For the money this thing rocks! Flush magnet switch so you can sit down with no locking. Tested in 18650 and 18500 mode and no battery rattle. Switch is extremely smooth and has a great hit to it. I don't sub ohm but I tested at 1.2 ohm , 1.8 ohm and 2 ohm dual coil. I have to say I have put my other devices to the side for the day. For the price you can't go wrong.
