Kensington keychain WiFinder sucks

Bob Rudis reviews the Kensington Wi-Fi Finder — a keychain-fob-sized Wi-Fi detector — on Wi-Fi Networking News and finds it sorely lacking:

I immediately tried it, since I have an open AP at home. At the time, there were no clients on the network, just the AP happily sending out beacon packets. The WiFinder didn't detect anything. I double-checked the settings of the AP and tried it again. Still no signal registering on the WiFinder.

On a hunch, I started up a couple WLAN clients and had them stream some music and d/l some game demos in order to create a good amount of 802.11b traffic. The WiFinder eventually did pick up the activity, but as soon as the traffic stopped (leaving the AP beacon only), the WiFinder couldn't find anything.

I was going to give their support organization some time to answer a few questions I submitted before contacting you and others, but when I was told that it would be 2 days before I would hear something, I had to start spreading the news.
