I have been trying to fine tune my new DOVO most of the night, and, I flippin did it. A succuessful hanging hair strand test I'm so happy!! I showed my wife and she said" thats nice hun" so I had to tell someone who would understand. I followed Howards advice and got the Radioshack microscope and checked it and rechecked it till it looked right. Thanks Howard and everyone for the tips- you guys are awesome!! I cant tell ya, it was so nice to see that hair pop in half. Thanks again!!
