The Dazzling Speed swing trainer is built for golfers who want real-time feedback and powerful results. Designed with four LED balls featuring a total of 160 precision-cut holes, it generates strong air resistance to accelerate swing speed and boost driving distance. The built-in LED lights illuminate your swing path, allowing you to make immediate adjustments for a proper plane—even in low light. Crafted with a flexible shaft, it promotes natural lag and smooth rhythm for a more rhythmic swing. To activate the LED lights, simply turn the switch on the ball to the right using the included key or your fingers. To turn the lights off, rotate the switch to the left. If the LED lights stop functioning after extended use, replace the switch using the included spare. To replace, gently rotate the old switch and pull it out; then insert the new one and twist to secure it. Portable and easy to use both indoors and outdoors, the Dazzling Speed trainer helps golfers of all levels develop consistency and distance in every session.
