This new version is fabulous. A friend of mine has the Afterglow AG9 (also made by PDP) and he likes them, though he says he has had a couple of failures. Needless to say, Im buying a second one of these for the controller that comes with the system. They also kept sandOut. So I am spoiled. I am returning the size 11 tomorrow with the label provided and I appreciate it very much, even though I was told I could keep or donate the size 11 I am returning them to you thank you again The size 11 1/2 came to days later and they are so great the customer service team and I really appreciate them o The Bluetooth setup is extremely easy to use and the quality of sound is excellent for the price point. I intend to give this program a try. So, if you want to take a chance go for it. I recently purchased these shoes for my wife.
