Relief and recovery for your knee – at home and after exercise

The SKG Knee Massager WS500 is designed for everyday knee massage – whether you want to wind down after a workout, enjoy soothing warmth on cold days, or simply treat yourself to a relaxing moment at home. It is adapted for use in scenarios such as post-activity recovery and for providing warmth and comfort when your knee feels stiff or cold.

Massage that targets the knee joint and surrounding muscles

The WS500 uses a massage technique with an eccentric wheel motor which, according to the product information, provides a more “kneading” sensation around the kneecap compared to traditional micro-vibration. You get a total of 5 massage modes designed to work on the knee joint and the muscles around the knee for relaxation and increased comfort.

Heat with near-infrared technology and three temperature settings

For those who appreciate warmth, the WS500 features 3 heat levels (45/50/55 °C). SKG also describes a built-in light matrix with 31 “rice bulbs” and 970 nm near-infrared technology for so-called “air heat moxibustion,” with rapid heating (stated as approximately two seconds). The heat is intended to provide a steady and comfortable hot compress sensation over the knee area.

Intelligent temperature control (NTC) and rhythmic heating

For more controlled heat, the WS500 uses NTC sensor-based temperature control, which adjusts the heat to keep it within a comfortable range and reduce the risk of overheating. SKG also describes “rhythmic heating” as well as intelligent compensation for temperature differences between the inside and outside of the knee.

Stable fit: patella support, anti-slip, and elastic straps

To stay firmly in place over the knee, the WS500 has a transparent silicone support for the kneecap and a construction designed to provide a 360° fit. The upgraded, recessed elastic strap is designed to reduce the risk of it slipping during use, and the material is described as soft and skin-friendly. In addition, there is an anti-slip surface with a diamond pattern and a more breathable strap design to reduce trapped heat.

Easy to use – large buttons and voice prompts

The WS500 is controlled via buttons on the device (“fuselage buttons”) and features voice prompts to assist during use. Temperature is adjusted using plus/minus buttons, and the design includes a special I-beam-shaped recess which, according to SKG, accommodates the movement needs of the knee joint for better flexibility while wearing it.

Battery, charging, and usage time

The massage is pre-set to 20 minutes per session. The battery is 2500 mAh (18.5 Wh) and charges via USB-C (Type-C). The product information states up to 80 minutes of battery life and that it can be used while charging. Voice and light indicators help remind you when to charge.
