Since there seems to be an art to devise a sensible baby monitor, I would like now but times indecisive parents share my experiences. We had our first child already the smaller Philips Avent without temperature. This now works relatively reliably for over 4 years. Relatively, because close to DECT phones can interfere with the reception, without you noticing it. When the schedules but keeping some distance, it is very reliable. Unfortunately, now there's only this successor with questionable important temperature indicator and much Schick-knacks. No matter. But when the second child came and I wanted to buy a second less possible expensive baby monitors for other environment when traveling, a Ansmann Sydney ran my way. This can be, unfortunately, in the sensitivity does not govern and I discovered my child crying in bed before the thing approached. So back to the dealer. Because Exchange me a Philips SCD 501 was then offered. Had stopped at the same price. The transmission was also good. But the parent had no battery, the baby part can not stock up on batteries and also was not adjustable sensitivity for response. Terrible for the price. So the Avent SCD525 was ordered and works very well. Incidentally, it is the only Philips baby monitor, which can be loosely bring to it, etc., for example when shopping or even a barbecue in the battery mode to operate. And since then makes another temp display sense if the sleeping child remains in possibly warm car. Conclusion: The Philips Avent SCD525 is according to my research currently the only baby monitor, which has a good transmission quality, can turn even with loud snoring or bed rustling depending on the setting, has a good grip clip at parent has a battery in the parent ( holding, depending on use for several days) and operate the baby unit in the battery mode, if desired. Whether it also songs, light, curtains, coffee cook or anything else can, is not important for us. The main thing is you can hear it when the child becomes restless before they cry or scream it starts. Oh, the way it as walkie-talkie to use toward child, only made with us from 3 years meaning. Before the Lüdde was just confused. So despite the danger with the signals of DECT phones to get confused nevertheless there 5 stars because it all can when used correctly, what we find important.
