Pre purchase research is always done before I buy any product. Ororowear was very highly rated. I purchased a vest through the Amazon website and the lack of a charger accompanying the battery was not clearly stated. My suggestion would be to have a charger included with any Ororo purchase since the product warranty is only recognized when the charger is used. I contacted Amazon about the missing charger and they immediately sent me another vest package. Prior to the replacement package arriving, an Ororo representative contacted me. Ororo rep Giselle was very knowledgeable and helpful regarding the lack of charger with the vest. I had searched on Amazon and the only Ororo chargers I found were included with the purchase of a second battery (which I wasn't interested in). Giselle was very helpful in supplying the charger I required and even shipped it at their expense. In closing I would like to reiterate that when an item is required to properly use a item, it should be included with the products purchase. Thank you Giselle and Ororo.
