Haven't used it really. My pod poi died the day I put the ultra on there
I ordered a set of helix light that included these. They add so much more to flow art. So much so, that I ordered another set to apply to my contact poi orbs, once they arrive. Very pleased that they are rechargeable and come with extra batteries when the time comes to replace them. Excellent Product for beginners to advanced flow artists. I definitely would recommend.
buy them, they’re more worth the money
Easy to use, very bright. Satisfying purchase
