Very durable, amazing color selections, battery life has been good enough, and overall an amazing price for what you get. Been playing around with them and switching to contact poi has been a bit of a challenge but worth it. I would recommend these for anyone starting to get serious with their flow.
I bought these for my husband, and he loves them! The quality of the rope and the led sticks + covers are great. He finds these easy to work with when he is spinning them, because the rope quality spins well with his hands. He likes that the LED sticks have a loop on the bottom in order to add weights. The custom colors on the sticks are a great addition, and there are a range of colors to choose from! You can customize your own led pattern, or use one of the pre-made ones, such as rainbow. The customer service is also great. One of the lights stopped working shortly after we purchased these, and after a quick support email + a video of the issue, they sent us a new one to replace it. They are very friendly and fast. Will definitely buy more in the future!
