Is WPS (Wi-Fi Protected Setup) a joke?

I have clients touting about the need for WPS for their offices, but after trying Linksys', Netgear's, and Belkin's both 11n routers and client adapters. It was more difficult than just setting up WPA2 key manually. Am I the only one thinking this? Or am I doing something wrong here...

the only method I found that works 25% of the time with WPS PBC method is...

1. Push the WPS button on the client adapter
2. Enter into the router's web configuration on another system and select WPS
3. Push the WPS button on the router
4. Wait for 5 minutes or when it feels like it wants to complete on its own
