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.
Easy to use, very bright. Satisfying purchase
These knobs are great! Not too big, they are rechargeable and they charge super fast, super easy to install. I will probably own multiple pairs in the future. Highly recommended. PS: The button may seem tough to press, press the opposite side of where the charge port is, it will click in a lot easier.
