Hi, so I just got a vamo v2 while I wait for my svd to be replaced due to a fault. I've read a lot on this device and understand that it should be set to no2 or rms mode. Problem is, when I do this the vape is really really weak. I'm using a protank. If I set it to 7 watts which was my sweet spot on the svd I get virtually no vapour, I get more vapour on my twist set at 3.4v. It's giving correct ohm readings. If I set it to no1 mode or mean, it vaper perfectly. I don't understand it. Is it safe to use in mean mode? Also if it's in mode 2 and I use volts instead of watts it vapes fine, very strange. Any help would be appreciated, cheers
