Matches the description pretty well (see photo).Charging capacity is about 222mAh.Charging was performed on 5V. So it's about 1.11Wh or 300mAh on 3.7V (its working (discharging) voltage). It appared to be 0.5mm thicker than declared 5mm (so there were problems with placement into device).I'm using it with old Jabra BT3030 bluetooth headset.Shipping & delivery to Moscow, RU was pretty long and took as much as 38 days. The parcel was fully tracked with default and free China Post Registered Air Mail.I did not communicate with the seller.
