Good approach, poor development

I found this article now been 8 weeks in use. In the event that I would only rate the unit, the supplied batteries and the extensive equipment, I could easily give 5 stars. Only this case is with many other buyers as little as true with me, because I have more batteries at home and not to exchange the entire set when considering buying a stand and exactly where the problems started. I use only renowned and well-tested batteries like Duracell, Varta and Philips. These are also changed regularly, so that it can not be due to the batteries. The charger works for me namely exclusively with Varta batteries. This lack of interoperability was more than annoying, forcing me back to another product to upgrade. Therefore, only one star.
