    • Best sleeping mat ever made
Style: Single
Ok, I do not ordinarily write reviews unless I am very impressed and this sleeping mat really impressed me. I have tried a variety of sleeping mats/sensors in the past and the single biggest problem with them all (other than this one) is that they require you to use your phone to record the sleeping data. With other mats, you need to remember to open an app on the phone and you need to store all the data on your phone, which gets very annoying after a short while. Not with this mat, the sleeping mat communicates with Withings directly over wifi and all your sleeping data is stored on their website. Your phone is just used to view the data whenever you want, you can delete the withing app from your phone and it will not erase the data. The other important thing about a sleeping sensor is the accuracy, a sleeping mat/sensor is no good if it is not accurate, and this one is meeting my accuracy standards. You do need to be careful where to put the sensor (they say under the sternum) but once you do that, then you don't need to worry about placement ever again, or even need to think about the sensor ever again. It just records your sleep every day without you ever having to think about it. This point is not to be under estimated, I have 10 years of daily weight data stored on the Withings website, because I use their weighing scale. And no, I am not giving them 5 stars just because I own their weighing scale, I would simply not bother writing a review if I was not truly impressed with the product. I am going to come back and update this review after 1 year, the true value of a good sleeping sensor is in being able to consistently produce a good measurement every day. Update after 1 month: 1. Robust: I have used it for a little bit less than 1 month now, and I have a reading from every day. This is a first for me, my previous sleeping sensors never made it so far. 2. Accuracy: Accuracy is not super good but not super bad either. If you lie still in bed and do not move, this sensor will put you down as "REM", and the other deeper sleep settings can be fooled too. I think i have to leave the bed or sit upright for it to think that i am awake, otherwise it thinks that i am asleep. If the sensor is able to measure my heartrate and i don't move much, it has me down as asleep. Not complaining to be honest, I am not sure how much better someone else can do either. 3. Speedy reading: Typically i get the results as soon as i get out of bed, within 5 mins. On a few occasions, it has take longer. Sometimes as long as 6 hours. I think the sensor tries to connect to the website, if it is not able to connect, waits for a few hours before retrying. Not sure exactly what happens in the few instances. But I have always managed to finally get a reading from the previous night, even with those delayed instances. I see a lot of negative reviews and I feel that this could be a cause of concern. When you don't see the results right away, you get nervous that the sensor could be broken. 4. Five Stars: Yes, I still give this product 5 stars despite everything. Competitors take note, this is the first time that a sleeping sensor has been able to track my sleep for as long as a month, and the data is stored safely in Withings website. I don't think any other sleeping sensor competitor can say they do as good a job, including the mighty Apple. I am afraid that making a good sleeping sensor is so hard, that people might simply think it is not worth the effort. ... show more

    • You will forget about it... in a good way
Style: Single
I've been getting into tracking my and my families health as we get older. Devices from Withings/Nokia all seem to feed right into Apple Health so I've been one by one picking them up. They are all Wifi + Bluetooth enabled making for an easy setup and easy use. Easier, more reliable, and often cheaper than Fitbit devices I've used. I typically sleep hot, light, and tend to thrash in my sleep. While I am not fully awake during these times I can tell I am not sleeping great. Having data from this device is helpful to cross reference with other happenings of the day. Did I exercise, when did I actually go to sleep, what and when did I eat, etc. I hope to use this device for data collection to create more full picture to help diagnose and maybe finally, for once, get a decent restful sleep. This unit only works for one person, so you will need two if you have more than one person in bed. I suspect kids and animals might mess this up too? Not entirely sure but the data has been helpful for me thus far. The device itself is also super clean, fitting nicely into your home with a soft finish, USB power, and a neutral heather gray color. That said I've wired it so you can see anything, but I can appreciate a good looking device. ... show more

    • Disastrous customer service
Style: Single
My sleep tracker failed after only 3 weeks. Unfortunately for me, I gave it a chance and missed my return window. Withings has no phone number. It's a nightmare reaching them through the chat. Long delays. Twice my chats timed out because they took so long to reply that I stepped away and then suddenly because I hadn't responded in 8 minutes and they closed the chat! Here's the deal. No phone number. The people in chat robotically recited the troubleshooting instructions from the website. I did all of that already. They didn't want to hear it. The problem is that my device went completely dead. It has LED status lights on it but they don't illuminate. I tried the steps - disassociate from the app, hit a hard reset button (hold for many seconds). LEDs are supposed to flash. No. I told the chat person that I want to return it. Response: use it for a few more days and get back to us if you are still having trouble! About using it. This 1-star is more than the fact that my tracker is dead. To me it seemed like it did an adequate job tracking my sleep, but my wife reported much more snoring than the tracker said. And I caught myself snoring a couple of times but when I checked the app in the morning those events were not logged. So I'm skeptical about the accuracy. We have a foam mattress so I installed it on top of the mattress under the topper which is what the instructions said to do. With a normal mattress you're supposed to place it beneath the entire mattress. So I would think it would be quite good at detecting snoring through such a short distance. I might try chat again to try to get warranty coverage. But it gobbled so much of my time already I'm not sure I want to invest more. ... show more

    • Great product
Style: Single
Great product it’s not atomic accurate but it’s great for home use and as close as possible with measuring all stages of your sleep. 4 starts unfortunately because it’s not Alexa compatible unfortunately. It was in the past but skill was removed from Alexa store. When it becomes again available I’ll change to 5 stars. All in all it’s great product and works good. ... show more
