Particularly impressive is the high range, this was mainly the decisive reason to buy. In built-up area this is of course reduced to a few hundred meters, especially reinforced concrete floors set the range to approximately 100 m down (test 4 Stahlbetondecken). However, the date was no other baby monitors, which are mostly after 2 brick walls already at the end. My neighbor has the bestseller Philips Avent, although that can compete with the rich functionality (except second station), but the range is not even close. The build quality is high. Would buy again at any time.
