Strong dependable lights, well-balanced housing which helped improve my poi handling into successful contact moves and behind the back tosses. High quality product, great price, amazing customer support.
The shell is good but the fitting poi for them are awesome :D. When you play with them on hard ground they mine broke with the while. But know problem i wrote ultrapoi and they sent me new ones :D great lights and a nice flow feeling. Can´t hit you that hard with the silicone balls and that makes live much more relaxed :D. The rope has a good livetime, too i use it know for one year and it´s still their.
I recommend this poi everyone i meet who is in need of led poi :D
