Pro's:
You might get slight improvements on a hardwired ethernet , maybe.
Cons:
Deceptively described as shareware. It is not. It is a commercial product you get to demo for 14 days and during that 14 days you are badgered to register for a 20 dollar a year subscription . Also , instead of speeding anything up it slowed mine down.

If you run a high end Mac with a good internet, it might help, maybe, we will have towait for proof of that but till then avoid.
