Does anyone have first hand experience with the Weegoamigo blankets?

On the site, they tout the blankets as great for the stroller and at home. I'm thinking these would be the heavy blanket to compliment the Little Bamboo Airflow blanket I am already sold on.

ETA: I'm open to other "heavy" blanket suggestions.
