Do anybody know something about Mirillis Action software recording ?

i was looking for some alternative for FRAPS and i saw on Steam Green light Action game recorder. It costs less than FRAPS but still you have to spend some money so I prefer to ask about any experience before I give a few dollars to someone. If you can help me with that i will be glad. Maybe you can advise me some other program if you do not know that an Action Software. Everything but not Fraps...
I will be very grateful
