Callaway X-22 Tour irons - any opinions?

Many thanks all. I bought a set today over the phone and I have never seen or hit one so I feel reassured after your replies.

Two rounds with Mizuno irons was enough for me! Lovely when out of the middle but not forgiving enough for my level of skill! Mizuno memories will stay with me though, especially a pure 180 yard 5 iron to 3 feet at Piltdown that felt absolutely perfect. This is tempered by a shot with the same club at Goodwood Downs last week. Hit a really long drive on a par 5 then caught the 5 iron slightly thin and it went nowhere. The punishment outweighed the crime and I knew at that moment that Mizuno and I are not suitable for each other!
