WMWifiRouter Vs Others

[Marvsway]

After reading a few posts here on Tethering and using your phone as a Wifi Hotspot, I decided to try out the WMWiFi Router (Trial Version). Works great! Very user friendly. Even A technology tard like me can actually use it easily. It supports both tethering and wifi. Lets me take calls and do other crap on the phone while still letting me surf the web on my laptop. Question is, for those of you that have tried this as well as the other apps like TomCodon etc, Is this app worth the $20 or should I save my money? The reason I ask is because, as I said before, I'm a tech tard and I want something that's relatively simple, no need for me to spend hours trying to figure out if it has issues, and obviously, I need it to be stealth (which I still don't know if it is). While on the trying to figure out subject what does Regediting do exactly?
