Amazingness indeed - ScottishGeeks - 08/08/2013
This was my first VV battery (Variable Voltage) and it is a solid reliable battery that has stood the test of time. I would heartily reccoment to anyone looking for a VV battery without the complicated set up. the only thing I would change is the lights ...red for cool to blue for hot seems a little backwards but ah well. get one today it's amazing!!
