How quickly does it warm up?

Most of our heaters and warmers give noticeable heat within one to two minutes. Exact times are listed in the product description.

Is it safe to leave running?

Our heaters are designed with safety features such as overheat protection, and many also have tip-over protection — check the product description for the exact features. Never cover a heater and always follow the instructions.

Will it work with UK plugs and car sockets?

Mains products come with a UK-compatible plug or adapter. Car products use the standard 12V socket found in UK cars.

How much energy does it use?

Because you only heat the space or person you need, you often use far less energy than heating the whole house. The wattage is shown on every product page.

Stable, snug and ready for action

If you love sport or spend a lot of the day on your feet, a close-fitting knee sleeve can give you extra confidence. A contoured gel pad surrounds the kneecap, while dual spring stabilisers on each side add firm lateral support. The fabric helps spread pressure across the knee and keeps it pleasantly warm, without limiting how you move. It's comfortable enough to wear all day and fits a wide range of sizes.

Why you'll love it

Gel surround: an anatomically shaped pad sits around the kneecap.
Dual springs: side stabilisers fit close for added support.
Stays warm: functional fabric keeps the knee feeling cosy.
Free movement: firm support that doesn't hold you back.
Day and night comfort: a stretchy blend of nylon, polyester, spandex and latex.

Perfect for: sports and training, active days, walking and long shifts on your feet
