Cool design

They are great for what they are. My first knob shells lasted me a good while on my OrbPoi, even though I've countlessly drop them on concrete/hard floors, and let kids play with them. My new ones that UltraPoi were quick to send me, will last just as long or even longer. They are easy to pop off, and easy to pop back in for when I need to charge the chips inside.

Thank you, UltraPoi!

This Poi WINS

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.

I’ve been spinning for about 2 months and these have made it very fun and simple to learn my parts and play with the assembly.
I would highly recommend any skill level to look into ultrapoi products.

Great Product!

I really like how each O-ring is always the same size and helps keep the housing of the handle firmly in place. Even when I stuff a huge knot into the handle, i am still able to use the aO-ring to hold it all together!
