They comply with the description and pictures. Heat function requiress 6x AA batteries which are not included (3x AA in each hands). Gloves are good also without heating to wear. These are very comfortable to wear. They are big. Connector should be on side, not on front. Is necessary be carefull, because is not thight connections. Connector is easy to disconnected without any problem inside the gloves, it is not comfortable. Connector on the side has to be more comfortable. I have not tried the heating function yet . When will be more degrees under the zero, i will test them and also the length of life of batteries. Should be more expensive, if the life will be only few hours. Better will be maybe with reachargeable liion batteries with button outside and not on the battery cover inside the gloves.
These are very comfortable to wear. Does require 6 - "AA" batteries. Compartment where batteries are held could be reconfigured so the batteries sit vertically along the wrist instead of horizontally. In addition, an additional strap to tighten the cuffs or wrist area would be nice. Wish there was a rechargeable battery system. I have not used these for an extended period of time, so I don't have any info on how long the batteries last from constant use. Instructions are not included (nor batteries) but it's easy to figure out.
