### 1/5 — Major flaw in how data is presented

*2021-07-02, version 1.0.2*

The app recorded I had 4 “minor” events overnight but you’re not able to view exactly what happened during those events such as a low/fast heart rate, low oxygen reading for example. Completely useless to show an event but not to specify what happened during the event. I even sorted through the oxygen reading, heart rate, and respiratory rate during the specified times it said I had a “minor” event and the parameters were normal. I called the tech support for Misimo and they were completely useless and had minimal knowledge of their product.

### 1/5 — Wasted Money, Useless Data, Cumbersome Device

*2021-02-11, version 1.0.2*

I regret not reading the reviews before buying. I assumed something with medical grade background would be stellar. I could not be more disappointed and annoyed. No where did explain that this product is disposable! $80 for something that lasts 7 to 14 days, and is cumbersome to put on and take off, and provides useless data in the app.

Every morning you have to remove the battery (no on/off switch), put tape over the exposed metal connectors, and replace the adhesive for the finger. And it still will only last a maximum of 7 - 14 days. 

The data in the app is useless. It provides a summary to show you had “events” and gives you a red dot for “major events” and yellow for “minor events” showing how long they lasted, but then does not explain what the events are.Some of my major events lasted several minutes, and multiple minor events lasted several minutes without telling me what it was. I called and Tech Support said they’d get back to me, which never did, and I emailed but reply said to “look at the overall trend.” There is a “Halo” rating. What the heck is that?! The overall trend of what?!

### 2/5 — Mediocre results

*2020-11-25, version 1.0.2*

First, it's not technically one use. The instruction manual clearly states it will last for 96 hours - that's just shy of 14 days at 7 hours of sleep per night. And there are enough sticky wraps in the package for two 7-night studies. 

The bigger problem is that the results are less than stellar. It shows some basic metrics (like every other sleep tracker) and does O2 tracking. But it also computes a composite score and doesn't tell you how. Worse, after the seven nights, the final instructions are literally "look at your trend and if it tracks downward, here's some tips for better sleep!" And the tips are basically exercise and no drinking. 

I was excited to have something medical grade to track sleep but this was a complete waste of money.

### 1/5 — Beware 1 times use

*2020-10-13, version 1.0.1*

Hopefully you did already buy the hardware. It’s a one time use ripoff. Buy a quality product you can uses as many times as you like such as a Nonin. Big disappointment.

### 1/5 — Bait and switch.

*2020-10-09, version 1.0.1*

No mention in any documentation that it’s good for one use.   Waste of money.     Sending it back, unused.

### 1/5 — 7-Day Disposable Device

*2020-10-06, version 1.0.1*

This is a device designed for use in a SINGLE 7-day sleep study.  Unlike all the other products this company makes, this is not intended for long term use.  It does not have a replaceable battery or even an off switch. This company makes an O2 sensor with a lightening cable and software to download and email a .csv file.  This device does not work with that software, it has its own sleep app. I could not be more disappointed. The web site and marketing material makes no effort to make clear these limitations.  As always, BUYER BEWARE.

### 1/5 — $75 sensor + app. BUT the sensor isn’t rechargeable.

*2020-09-23, version 1.0.1*

This hardware is the best American medical device engineering has to offer.

High grade O2 sensor and low profile Bluetooth connectivity in a low profile form factor from a leader in hospital grade equipment...

And it is ENGINEERED to FAIL.

Consumables drive up the cost of health care.

Thank god Apple Watch is going to have O2 monitoring.
