WASOTO Unisex Heated Gloves Rechargeable (Open Box)

Bought these in April. Have used them every day for about the last 60 days. I use them, charge the batteries overnight, and use them again the next day. Batteries last for about 4 hours before dying (and that's on the warmest setting which uses more power). I work on a golf course mowing greens and fairways in North Idaho at 4 AM. I literally mow the greens every day which is the reason for using them every day. Another plus is when they are charging, the batteries do not get warm from charging. A lot of times a person charging a battery feels the warmth from the battery charging. I get no heat from these batteries charging. The only heat I feel is when I put on the gloves and turn them on. Thank you for a great product. I would give six stars if I could.
