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.
These ultraknobs are fantastic! They have great battery life and recharge fairly quickly. I've been using them all week and only have had to charge once. The customization of the led colors is pretty nice. There are many colors to choose from with options for brightness and patterns. For me the biggest benefit to purchasing them is how light weight and durable they are. They don't really hurt anymore so they make great for practice and I don't have to worry about knocking someone's teeth out at an event. Lastly customer service is amazing. There were a few hiccups before my package got to me, but they quickly resolved any issues I had, and even replaced a broken part free or charge.
