Sean and Prisna at flowtoys.com are good friends of mine. Their flowlights are my favorite LED toys in the universe, and I hope to help rally the community behind them (which will be easy as long as they keep making the best toys.)

The flowlights are bright, durable, and come programmed with many modes. They take single rechargeable AAA batteries. They are sold with various shells, so you can have poi, wands, staffs, and other toys, all with one set of lights. They also make great handles!

Crystalpoi make a particularly awesome pair of rechargeable LED poi. Make sure you get the "flow mass" covers to add a little weight. Both flowlights and crystal cases are now available on homeofpoi.com and flowtoys. Remember to use "playpoi" as your referral code!
