I like it for the reasons stated above. Especially the using of different ohm cartos, or atties. On my last order of cartos, I ordered among others, three boxes of 2Ω cartos which I no longer use. But, no problem, just dial it in for 2Ω. Plus when I got my first VV, I had some 2.5Ω that I no longer used, but was then able to use them up. So, they just come in darn handy, and so versitle. I can't wait to get a VV Grand to add to my roster.
