I gave up a perfectly functional Netgear G router with extended range and spent $200 for a Valet Plus (M20) and a Valet Connector to provide internet to a new game computer for 11 yr old son. My #1 concern was internet filtering - so I bought the Valet since it parental controls are a big selling point. My #2 concern was Wireless Range - so I bought the more expensive M20 version.
The Parental Controls are a joke. You can set it to Child or Teen - thats it. It will block out all WEBSITES that are inappropriate to the age setting. Google is an appropriate website - so you go to Google Images - type in "porn" and up pops 10,000 porno images - of course if you click on the actual image The Valet will block that, but it doesn't block the search - so you have to go to Google, and Bing, and etc... setting up Locked Search controls. Do not purchase this thinking that it is a filtered firewall like the kids have in school. Its a half baked concept. By the way - AdamAndEve.com is not a blocked site - apparently its a legitimate shopping site for kids. The Valet allows you to block individual sites - up to a total of 8! If you are buying this to protect your kids, forget it. Go with Net Nanny or something.
As for range - and the Valet Connector - I am 75 feet from the router and I have two of five bars. The Valet Connector is just a USB wireless adapter plugged into a stand - its nothing special.
If you are a total computing moron and don't know how to configure Microsoft Word, then this router is for you. If you do not know what USB stands for, buy this product. If you are comfortable using the words router and ethernet, then buy any other product for half the price with double the features.
HUGE DISSAPOINTMENT!
