Today i got my vamo in the mail i was so happy

only bad thing is that the top is a little bit crooked and i dont know how to get it in rms (no idea what rms does but every one says its better

) so if some one could tell me that that would be awesome !
No 1 is an average. In real terms - it fires higher than the setting on the display. So, for example, you have a 2.6 ohm attachment (cartomizer or clearo), and set the Vamo for 7 watts. Instead of firing at 7 watts it fires at 9.7 watts - quite a difference. I didn't just make up those numbers - they are test numbers from tests done on Zmax's - which have the same chip as the Vamo. Some vapers like a harder hitting setting and use this - not that many tho.
In No 2 mode, RMS, what you set on the display is what the Vamo will fire at.
So again, lets say you have a 2.6 ohm attachment and set the Vamo for 7 watts. In no 2 mode it fires at 7 watts. So its more accurate, and you don't get any unpleasant surprises from it firing higher than you wanted.
RMS mode is NO 2 on the Vamo. Just hold down one of the small buttons for about ten seconds until you see either NO1 or NO2 on the display. Whichever one you see is the one its on. So if you see NO1 hold one of the small buttons down until you see NO2. Then leave it there.
