Shipping quickly but the battery does not charge 2h. The seller told me to leave the responsibility up to 12 hours (3-4 times), she always discharge into a straight. Very bad!
Speedy shipping - Purpose, this item can not run for 2 hour. Following seller's advice to plug in for 12 hours (3-4 times) and let it Discharged, it is still down in 1h. What a life-short battery!
