I have this sphygmomanometer now for two weeks and I am "now" very satisfied. For me it was mostly about the editing on a PC. It has just not worked out. Then I called the customer service. 0731-39890. Phone a friendly lady, Mrs. Sailer. After I had told her everything, the question was: "Do you have the date set correctly" Of course I had set a wrong date. This can be easily overlooked. After I had set 2014, the storage and processing work easily on PC. I have the operating system Windows 8.1. A small mistake with big impact. The device I can only recommend. Three-year warranty. I can say nothing about the battery consumption. I immediately the supplied batteries (2xAAA) replaced by Eneloop 2xAAA batteries. After two weeks, no negative effect. It's also nice the second memory. 2x 60. I will report later. The customer service is very good. I believe that it is important.
