I have been using it for weeks. It does an excellent job and costs nothing.
I'll have to do a comparison tonight - if either Klip.me has improved or the readability send-to-kindle does a better job I will be very happy.
EDIT: Never mind, it looks like you can just add a username. Oddly, it tried to get me to log in/sign up when I tried it earlier, I have no idea why.
