2.5 stars because it works. But every time I use it it opens a really annoying, dangerous looking spammy ad site and makes a really annoying beeping sound that tells me there are viruses on my computer and has a button to clear them. That's really a no-no. If you want to get malware on your system that's a good way to do it. The website that converts the videos to mp3s is also really slow to download from. So I'm removing it from my computer and looking elsewhere. I'd be willing to pay for an add-on that just does the job without all the annoying and possibly dangerous ad sites that pop up. It's a shame that the developers took the underhanded sleazy approach to monetizing their work. They have a donation button, and I would certainly donate if not for that. The slow download speed is a minus too, but nothing compared to the awful ad pop-unders.
