This was posted on KVR, and the fact that it,s a Polish site and the download is an installer has put people off.
I would definately recommend downloading though. There are ten Vsti in the pack. Eight synths that are emulations of classic synths, a drum machine and a rythym box.
The synths are really good, a few are damn good. I'm having loads of fun with these.
Give em a go.
