Good Tumblr Plugin Like Publicize?

I want to be able to post my wordpress posts to Tumblr. I read that they added that ability on wordpress.com through the Publicize feature but not on self-hosted blogs.

I looked for a plugin to do this and one came up called Tumblr but it only has two stars. I don’t see anything that has comments for me to know why it’s rated so low so I don’t want to install it in case the low rating has to do with functional issues that mess up your blog.

Does anyone know another plugin that works well for sending posts to tumblr? Thanks!
