We have used the Sense-U diaper clip breathing monitor for six months now. Overall, I would HIGHLY recommend it to anyone with a small baby and ~anxiety.~The good:•Accurate & sensitive readings - Have tested in my own hands, laid on a still surface, etc•Very easy to use/put on•Decent battery life•Alarm is loud and WILL wake you•Room temp & humidity readings are very useful•Option to pay monthly fee ($5-$6) to get access to all of the info trackedThe bad:•If you don’t pay that monthly fee, you only get live readings, never the history of the night etc•Because I pay for the history, I can see that the device does at times stop reading for 5-10min at a time. At most this has happened 3 or so times in one night.•Sometimes glitchy - Have had to “forget” and reinstall the device through the app many times, but it always works in the end, so more an annoyance than anything•If the device loses contact with your baby in the night (ex: my baby rolled on her side and her diaper pooched out away from her belly), you will get a false alarm. That said, I’d rather have a hundred false alarms that assure me the device works, than one that doesn’t. ??My 6M old baby hasn’t gone to bed a single night without wearing this breathing monitor. In case you are comparing, we also have the Owlett smart sock and the Snuzza. This device is far more valuable to me when it comes to SIDS & rolling over while asleep concerns. With real time readings, custom alert settings and an alarm (which blares through both the home base and your phone), I feel a lot calmer at night knowing that if something goes wrong while my baby is sleeping, we will quickly know. This is one of, if not our top, best buy for baby.
