I'm really open range expected at this product and have me not want to be put off by the negative reviews. Today, the product arrived and after multiple Try I can only say that this product is absolutely useless for my purposes. The most accurate way to measure it, when setting up it directly to end it. Still, I've got almost 10 different values within 15 minutes - 37-38 degrees everything was there, partly in direct succession deviations of 0.4 degrees. Such a rough guide, I really do not need, because if you have a body temperature of 37 or 38 degrees, now makes a significant difference. Unfortunately, the product is therefore back - I did not expect at a brand like Braun.
