Yes, it is a legitimate company. I have Screen Recorder, and it is a legitimate and useful product. They seem to have only one person as the initial point of contact, so sometimes they don't get back to you immediately, but they eventually will.
It is not a scam. The software is 100% workable and does what it claims well. Had run into software problem which was immediately solved by the customer services.
It is not a scam. I worked closely with one of their support staff so I could get the M4V converter to work on my computer. They were extremely helpful.
So far, my experience with their software is horrible. It is buggy as hell and can't run through a stack of songs without freezing or encountering an error 1-4 songs in. It monopolizes your computer too, and you have to sit there and watch it and refresh the library every time it hits a snag. So I have about 433 songs to convert and its going to take hours. Save your money.
