ResMed S+

Does anyone have experience of this device or have an informed opinion? Looks a bit of an expensive gimmick to me but maybe I'm wrong.

I have tried several devices over the last year, as an attempt to track my sleep patterns and quality, including the ResMed S+, and it was not reliable and a bit random.

I don't believe their radio technology can really track breathing patterns that well remotely, unless sleeping in a perfect position (e.g. on the back), and having nothing between the body and the device (e.g. no CPAP tube). Also, some functionality relies on the smartphone, which has to be kept nearby (e.g. smart alarm, sounds to fall asleep etc).

A fitbit charge 2 or Alta HR wrist band, or a Jawbone UP3 wristband (now discontinued/out of support, so can be bought for cheap) provide better and more detailed sleep data, for a fraction of the price (and they can do other things too!). Those devices can measure heart rate and motion, and can derive the sleep stages from that information.

The Dreem headband, just announced this week as a final product, looks very promising too, for tracking sleep stages at home, as it's a device with brain wave sensors/electrodes (EEG), but it's expensive ($500!), and won't be dispatched for 3 months: https://dreem.com/features.html

It's not just a sleep tracking device, but also claims to help fall asleep and keep the person longer in deep sleep, by playing specific noises/frequencies through the built-in bone-conducting speaker.

ResMed haven't really evolved their S+ sleep tracking device over the last 3 years, so they have probably given up on such technology to track sleep patterns.

Agreeing with tedtomato, I'll add that although it is kind of gimmicky, it has An App!
And the app will give you a "score" and advice such as "Try drinking some warm milk at bedtime" and "Your room was too warm last night."
It can play soothing sounds on the tablet or phone. So if you're looking for some kind of gadgety feedback or a placebo, $50 is not too bad.

$50 is not too bad indeed.

However, the OP is from the UK, where the ResMed S+ device is sold for three time as much, around $160! For that price, you may as well get a Fitbit Charge 2 wrist band, if the main intent is to get some measurement on sleep stages and sleep quality.

Thanks guys, I thought maybe the replies would be along these lines. I will tell my partner to drink some warm milk, open the window a little wider, and play some white noise
Very expensive in the UK even at the reduced price of £99, so not worth the risk experimenting.

If it means I will have to remove my aluminum foil hat, I think I will pass.

Maybe I should keep it. The "voices" sometimes want me to do some pretty scary things.

S+ is under $35 now on Amazon! Has anyone tried the Dreem? It is "on sale" at $400...

S+ is worthless, even at $35.

The Dreem is promising, but very little reviews yet.

For now, I would recommend the Fitbit Charge 2 if you want to track your sleep stages, as it does not do a bad job (and I have compared it against a PSG sleep study).

I also would suggest looking at the FitBit Charge 2 (or there's another one I think that does heart rate and sleep but I forget the model name).
Heart rate is factored in and the FitBit doesn't rely on movement alone to try to figure out sleep status. No movement doesn't equal asleep...I can lay perfectly still and be totally awake....so I don't put much faith in anything relying solely on measuring movement as a way to determine sleep status. Now using movement and heart rate...I can see the science behind that and while it isn't perfect...it's pretty darn good.

I just got a FitBit Charge 2 about a week ago and so far it seems to be decently accurate. It has missed a couple of known awake times but overall not bad and certainly more accurate than some gadget sitting on the night table that isn't even touching you.

I bet I could fool the ResMed S+ thing really easy.
I have no idea about the Dreem. Had to look it up just to see what it was.
