fast ship. secure packaging. fit and finish is great. for the $$$, you cant beat these. 4 guage is the way to go. extra long cable length with great quality insulation. the glowing pos/neg cues work well, but are kind of a gimmic imho. if you cant tell the difference between pos and neg, you should probably call AAA. clamps are sturdy and solid with very strong springs and good bite on the pole.  great product. highly recommend...
