Actual keyboard?

They sell a keyboard case for iPhone that sits down below the screen like the old BlackBerry phones did. Anybody using these? I need real keys pretty badly, but I don’t want to drop $140 on this thing (or $85 used on eBay) unless it’s stellar.

Anybody got one? Would appreciate honest feedback. Thanks!
