At our Newborn Essentials class before our child was born, I asked the instructor if she had heard of the Woombie.  She said that she had heard very mixed reviews on it.  Nevertheless, I was excited to try it out since my baby broke out of every swaddle.  He hated it.  He was only a few days old but it didn't seem long enough.  It sorta looked like his head was attached to a bag of angry kittens.  I would say try to buy at a store so you can take it for a test-run and see if your baby will tolerate it.
