Works well and highly recommended! I went searching for an application to make alert tones after I used such an application on my Palm Centro... And this is the perfect solution! It's awesome to see that Ogg Vorbis files are now supported  as virtually all of my (mobile device) music is encoded in this format. With an easy-to-use interface  this simple-but-powerful application is highly recommended for anyone wishing to create their own  personalized alert tones!
