Both broke within 1 month. Will not keep charge
I ordered an O-Pen battery, said I would receive email when confirmed and shipped within 2 to 3 days. After 6 days I called customer service, once I got through, solved the problem and received my product when was told it would be received. It was appreciated.
Amazing. Fast shipping.
These are THE BEST pens Ever!!!
Overall very easy experience. No problem with ordering / receiving / using the battery. Will certainly purchase again.
