The Silva is small yet robust, has the features you need wirklichg, is very easy to set up and easy to read the results. The most important feature is the small security cord which can for example with a small clip as Additional Services security to the clip on the device can clip to your pocket. This is the lose of Silva virtually impossible. Since Silva's so easy would you fix the 'main Clips' not at all remarkable.
All in all, buying the right decision and I would buy it again. Price / performance, moreover very good!
