Beware of poor quality products. We bought a $30 rechargeable pen. Used it twice in two days. The battery died. We went to bed and put it on the charger over night. Woke up to use it, and the battery hardly charged. The pen button only turned yellow, not green for full charge and wouldn't burn to blow smoke at all. Tried to mess around with it for a few days, trying different chargers ect. It's pretty much garbage. Went back to the store and they wouldn't even exchange it. Definitely seems more like a $3 pen from Alibaba.com or something. For this price I'd recommend just buying one off Amazon. Free return and money back. This is why it's hard to support small businesses.
