I would NOT recommend purchasing from Zetronix. Before buying an audio/video pen recorder from them, I spoke to "Israel" in customer service, asking some questions about the product. He was speaking so quietly that I could barely hear him. I asked him to speak up, but he told me that he could not speak any louder because it would disturb the other people in his home. Yes, it would disturb the other people in his home. I asked if it was more important that he deal with customers and do his job well and he said no. I suppose I should have decided then and there not to purchase, but the pen they offered had features that I could not find elsewhere. I received the pen recorder from them and it turned out to be defective. Different colored lights were supposed to indicate when the pen was charging. It did not do that. I called and spoke to Israel again who said there would still be the 15% restocking fee and that I would have to pay for my own return shipping. I repeated that I should be fully refunded and have free return shipping as the pen was not performing as it should have. It didn't matter to him. I then wrote 2 letters to Ed Shklovsky, the CEO, the first on August 17th and the second on September 13th. They have both gone unanswered to this day.
