"Has lots of incorrect matches and fails to upload"
It's free and is *mostly* correct in finding updates.
Resource hog when scanning. Lots of false positives with respect to upgrades required. Fails uploading results to server (WireShark scan shows 500 server error returned from web service call).
Not great, but because it's free and finds most of the updates I require, I'll keep using it for now until something better comes along. Very labor intensive going to download each update one at a time from the scan result list (and the list isn't being kept updated correct since the upload results to the web service fails every time).
