I had been searching the Internet for a way to change my computer's IP address. No one seemed to have a decent answer; many of the answers involved complicated changes to my computer's settings and to the settings of my router, etc.. Then I stumbled upon this product, bought it, installed it, and have had no problems using it. I wanted to change my IP address so that I could access a political discussion forum that had inappropriately banned me. Thanks to this product, I am able to once again engage in dialogue at that site. And now I don't have to worry about being unnecessarily banned ever again. This is such a great, easy-to-use product. I'm glad to see the company has headquarters in Encinitas, CA -- I live in San Diego myself. Always like to support the local businesses, you know! Thanks again!
