Ordering the gloves is confusing because there are different types of gloves merely designated as “black-02, black-03” etc. The image shows different textures but there’s no description to indicate the differences. I ordered Black-02 and they work well. Measuring your hand accurately is key.You cannot pick up a coin with these or even type on a keyboard properly unless you do the two-finger approach because they are too thick for that. However, the finger tips do have different material that work adequately or barely on touch sensitive phones and tablets.The On-OFF power switches are on the cuffs and are bright lights especially in a darkened room. They are easy to press with a medium degree of pressure.Although effective, most of the heating takes place at the back of the hand and fingers.There are three levels of power/heating.Initially the gloves need to be charged for at least 4 hours. The gloves do lose their charge if they sit unused for three or four days. The biggest problem with the gloves is that the batteries are too thick and once they are inserted into the glove cuffs, it becomes really difficult to put them on. The bulk of the batteries really tightens the space for your hands to fit and it becomes difficult. Imperfect and annoying at best although still workable. Otherwise the gloves fit perfectly.
