    EXCELLENT transaction! GREAT product, GREAT price and SUPER FAST SHIPPING! Very satisfied with my purchase and would definitely buy from again. The only improvement I would suggest is to add shipping info once it's been shipped. I kept watching the page, waiting on shipping info and a tracking number and online, it looked like it hadn't shipped. And then it was on my doorstep a couple of days later! Great shipping speed but I would have liked to know it was on its way.
