Agreed, I use my Vamo as an Ohm meter, or my voltage checker to check my Ohms.
Aside from not having a USB connector, there really isn't much of a difference.
I don't see why "carrying it around" should be an issue...I rebuild at home so the Vamo just sits right next to my Helping Hands, in fact, since I never use the Vamo I may actually glue it down to a hard surface.
