I did a lot of research before I made the decision to purchase a Ceptics converter. However, I purchased and paid for the one I wanted and received a confirmation for a different Ceptics converter, so I sent several emails telling them not to send me that one and asking several questions. I quickly received replies and even videos from 3 different people explaining that the one I wanted was discontinued and the one that they were sending was even better--a better connector for the adapters, more adapters, a little more power, and even sent me a video demonstrating how to use the connector. After asking several more questions, I told them to send it, and I received it 3 days later (free shipping). They were right that this one seems to be great. Of course, I haven't been able to try it yet because I am not traveling until August. I will let you know. By the way, I had asked other companies questions and never got answers.
