WiFi Diagnostic Scanner

Being in on Bank holiday has led to me doing one of those "Pointless eBay browsing sessions" that has lasted the best part of the morning. :d



Anyway... Came across this. A Wifi diagnostic scanner that connects to your iPhone/Pad/Pod etc.

Has anyone had any experience with these? Trying to work out whether It'd be much good for £12.
