Every vaper should have a multimeter. They are invaluable when your testing things like voltage and resistance. This particular model caught my eye because of its portability and price. I especially love how the leads can put parked on the side - so you don't have wires going everywhere. Great to throw in any vape box or to bring to vape meets. For $9.95 its far better than the generic brand sold at fasttech and harbor frieght. WHERE: >>> HERE <<< $9.95
