I now have the WS-30 since about 2 weeks, got my "old" abolished because they only let on, when it just fit itself. With 99, the WS-30 is not exactly a bargain, there are others, some cheaper alternatives, of which I can imagine that they are not worse. I've decided yet for the WS-30 was that I bought at the same time the Withings Blood Pressure Monitor and thus arises for me the advantage of both devices with the same app and the same online portal to use. Anyone who thinks at this point "what a gimmick!", Should not his time continue with the reading of reviews on this unit waste and buy a proper balance to 50. All others I can only say that I am really pleased with my purchase. The WS-30 is as far as I can see the most favorable balance of Withings and sufficient for my purposes from perfect. If you have the scale and once registered (incl. Registration in the WLAN), it is after weighing out the weight and the current BMI and reminded not to forget the umbrella, the rain probability should be at about 70%. The latter function was added later and the manufacturer assures to continue working on new features, so they can be put to all users automatically available, software updates are indeed possible on the Internet connection and I understand that the upgrade was at this function automatically. All measured data are provided in an easy-app and an online portal. The app at the same time provides the opportunity to other data such as. To capture the spilled steps to present and wish to remember a variety of health-related things such as weighing, for example. Is to measure his blood pressure to go to bed on time or enough to drink or to make an after-dinner walk to reach the daily target step. That may not be an issue for some, I personally have but for example in the past, forgotten almost daily, my measure blood pressure (doctor's recommendation), which is no longer happens, since I use the app - my daily life is a bit hectic and you forget every now and then the things that are good for you. Motivating is eg. The opportunity to invite your friends out and make a competition from the achievement of the target step. In conclusion, I must say that I would buy the WS-30 despite the price again.
