We created the Sunbird to give people a more accessible and affordable option while still keeping the feel and performance everyone loved in the Hummingbird. We started with the basic Hummingbird competitive v-shape profile and tweaked the weight distribution to maximize the performance in an all aluminum form. Right from the first throw you'll notice the same light and powerful feel on the string that the Hummingbird is known for. It has great stability and spin power, and if you're looking for speed you're really in luck! The Sunbird is fast, maybe the fastest yo-yo that we has released so far!
