Ergonomic anti-slip handle: Shaped to fit the curve of your fingers for a comfortable, secure grip during use. Specifications Resistance range 5 to 100kg, adjustable Spring material Stainless steel Counter Electronic, automatic Grip Ergonomic, anti-slip Start at a low resistance and increase gradually as your strength builds. If you are using this for rehabilitation after a hand, wrist, or forearm injury or surgery, follow your physical therapist's or doctor's specific guidance on resistance level and progression rather than the full range this device offers, since increasing resistance too quickly during recovery can risk re-injury. For general fitness use, choose a resistance that challenges you without straining the wrist or forearm. Use it for hand and grip strength training at home, tracking progress with the built-in counter.
