O'PRO9 Smart Diaper, Bedwetting Alarm for Seniors, Smart Wearable Wet Diaper Alarm Sensor & Real-Time Movement Tracking Monitoring App, Instant Alert Notification Reminder, Prevent Elderly Diaper Rash

I never write a review this time I just had to. The product that I received doesn’t receive a signal unless your phone is less than 2 feet away. I tried everything I don’t even know how the product works because it wouldn’t send a signal to my phone. In other words, it wouldn’t connect unless you’re literally right on it

I'm not one that often writes reviews, but given all of the one-star hate this product has had, I really felt that I should share my experiences with the sensor. We are using the adult version. In short, it works, but you may need to tinker with it a bit to figure out how/where to place it, how to set the sensitivity, and how far away from your phone you should expect it to work. Our experiences are below:Placement and Sensitivity:We use a combination of brands, absorbencies and inserts with our diapers, depending on day or night, at home or outside the home, travel or away. We've been able to get the sensor to work with every combination we have used, but for each one its important to figure out where to place the sensor(s) and how sensitive to set the app. When we first tried the sensor, we attached it in the lower front of the diaper and it alarmed immediately on the first wetting in most cases - too soon! This meant that much of the diaper was not used. Ultimately, after some experimenting, we ended up using two sensors, (the app handles this) one attached on the upper front, the other attached slightly up the back. When both sensors had alarmed, we knew the diaper was wet enough to need changing, but not yet uncomfortable. We needed to experiment to get the placement right with the different brands and combinations.Type of Diaper:Although the sensor is designed for the permeable "Cloth like" nonwoven covers, it can be used with cloth diapers as well (just insert it between the cloth and the diaper cover, adjusting the position as needed) or with "plastic backed" diapers (use an insert, place the sensor between the insert and the diaper, and adjust the position and reduce sensitivity as needed)Range:This is a bluetooth low energy device - that limits its range. Our experience is that its range is about the same as other BLE devices, about 15 meters (45 feet) indoors, a bit more outside, but as long as the caregiver with the phone is nearby, it works.Room for improvement:Battery life is less than expected, a month or so is about all we get with the batteries. it might be a cool improvement to redesign to use rechargeable Li-ion batteries instead of single use.The app could also be improved - provide the ability to "link" sensors if you are using more than one on one wearer, provide better access to wetting/humidity/time/temperature data (it seems to be cloud based so this should be easy) and provide the ability to customize the alert sounds per sensor/person. Another app improvement would be more customization on when the alert is triggered - better configuration in terms of humidity and temperature data.If you are a bit patient and willing to experiment a bit, you can probably make the sensor work for you!

This product advertises 30 meters (about 90 feet) of bluetooth connectivity range. That number is typically given on many products as a theoretical max range, given ideal conditions, and a direct line of sight to the device.It doesn't come close.First, it's a small device with low power requirements. Second, it's designed to be worn underneath clothing, and is positioned between the legs, putting a lot of signal-blocking human in the way.I'm lucky if it stays connected when I take my phone out of my pocket. I can't imagine how a caretaker could stay connected.Other than that, it's a little finicky, but seems to work. I'd prefer a sensor that could attach to higher capacity plastic backed diapers. It's also not waterproof, so be careful not to get moisture inside during a change. If you do, remove the battery, then use some isopropyl alcohol to evaporate the water away, and it'll work again.

Does not work. disconnects from smartphone constantly. and it doesn't know if diaper is full. I had it set all the way down to the lowest setting to pick up humidity. still no alarm when diaper is full

After spending 10 min trying to get it to pair (no instructions included), I finally decided to pry it apart to see if the battery was dead. Amazingly, there is no battery at all! These things are exceptionally difficult to open. It amazes me that there is no battery in place.
