If you're dealing with a broken throttle on your electric scooter, this QS-S4 LCD replacement has been a lifesaver. It works with a bunch of popular models including Kaabo Mantis, Speedual Mini, Grace, and Zero series scooters. The display is super clear and shows your speed, battery level, and other important info at a glance. Just make sure to check your current throttle against the photos since compatibility can vary between models. The installation was pretty straightforward if you're comfortable with basic scooter maintenance. It handles voltages from 36V all the way up to 72V, so it's versatile if you upgrade your scooter later. There's a protective film on the screen when it arrives - don't forget to peel it off for the clearest view. The buttons feel responsive and the throttle action is smooth without being too loose. Much better quality than I expected for the price. My scooter feels like new again with this upgrade. Just double-check your model compatibility before ordering to avoid any issues!
