Speevers is a juggling company based out of Israel that is now making LED and practice poi. They sent me a set of their Super Soky poi to review, including their new Jupiter ball LED heads.
The good news: I really dig the twist they've put on sock poi. They're just as fun to use during the day as they are at night.
The bad news: They're incredibly hard and may not be the best set to start out with.
