These work well in moderately cool temperatures. To get them working at their best, activate them 10 minutes before going outside. This allows them to warm up beforehand. Switching them on outdoors in the cold will make them take longer to heat up.

The product matches the provided description. It is advised to purchase powerful, rechargeable batteries immediately, as the included batteries are not recommended.

The product description is inaccurate and misleading. It claims to heat fingers, which is untrue, as the heating element is located on the back of the hands. Despite this, the gloves are otherwise of good quality and provide effective heat. It's disappointing. Two stars are deducted due to the misrepresentation. However, delivery to France was very prompt.

The gloves are a good size. While they don't feel extremely warm, perhaps only around 40 or 45 degrees, you can feel some warmth. They seem to be well-made and feel nice to the touch. The seller included a gift, which I appreciate.
