For a device the size of three fingers, the Checkme™ Pro Vital Signs Monitor is amazing. You can read the functions; I won't re-hash them here.
* The separate but included blood pressure cuff is convenient, comfortable, and simple to use. The device and system elements are accurate within expected limits in spot checks against Welch Allyn diagnostic instruments, and, after months of use, the Checkme Pro has proven reliable. All parts of the system are sturdy, appear well-made of appropriate materials, and have functioned flawlessly -- cabled and wireless.
* I bought the device for on-the-go self-monitoring during the novel coronavirus (CoVid-19) pandemic. I wanted to be able to measure, visualize, and store key vital signs: pulse rate; oximetry; rudimentary heart function (single lead ECG); external, non-contact (forehead IR) temperature; and, systolic blood pressure (algorithm estimate after calibration with bp cuff). I have not yet used the Holter monitor or overnight SpO2 monitors. The package supplies a few ECG electrodes; standard 3M electrode patches work as well. I don't have a Windows computer, so I have not tested the PC software, but if it's as good as the rest of the system, Windows users should be pleased.
* The Checkme comes with a stretch neoprene glove that stays out of the way yet provides excellent case protection, a lanyard, and contains an internal, rechargeable battery good for at least a week of hard use before recharge with a hard-to-find USB cable.
* The companion app for iPhone (and, I believe, Android) captures readings from the Checkme device via Bluetooth. Data transfer takes place on demand, and it takes only moments to move measurements from the monitor to your phone where they display beautifully, may be saved, and/ or sent via email to a healthcare provider or record storage.
* The screen on the Checkme is sufficient for a quick ECG review, and an on-board algorithm will alert to (but not diagnose) irregularities. Of course, other data such as SpO2, temperature, etc. are listed in date/time stamped tables. Data remain on the device following transfer to the phone app, and must be deleted manually. (This is a Good Thing.)
Finally, customer service at Getwellue.com is first rate ... amazing. I requested a soft copy of a Checkme-related document. I received it via email in a couple of hours. I had a question about a Checkme cable. A customer service representative from Getwellue provided what I needed immediately.
My only concern is the proprietary nature of system components and cables, but dealing with Wellue customer service has convinced me that, should replacements be necessary and unavailable locally, Wellue is capable of supplying what I may need quickly and fairly.
All-in-all, a game-changer. If the pandemic gets worse, perhaps a life-saver. Well done!

As a physician I found the device very useful for primary care patients. Small, portable and full of options. It can also help patients at home communicating their data with their primary care giver.
Customer support is also great.

it is comprehensive and very easy applicable and it help in primary decision for clinical situation even when you are at home
and I hope will be more study about it and its accuracy

Useful. Gives all the information I need. Some unclarities in the manual (it's inconsistent with the device when doing ECG measures (Method D, Lead II - right wrist to left lower abdomen, paper illustration is right shoulder to left lower abdomen, text says right wrist to left lower abdomen, quick reference card says right shoulder to left lower abdomen, device says right shoulder to left lower abdomen and Android recorder software shows right wrist instead of shoulder). Also temporal temperature starts with temp, then says to move around temp, but also to move to forehead, and then seems to indicate the temperature is forehead... so it's confusing. Is it temporal or forehead temperature (knowing there's normally a .1 °C difference between the 2 areas). Also it would have been great to ship (for that price) a specially designed carry bag. :) I've had to order one generic that sort of fits. But the device itself I'm really happy with. Four stars because of the confusion here and there.

Small enough to take any where. Pretty good for its size and capabilities. Waiting for iOS app that will transfer data to the phone. Would be nice if it can be integrated with Apple Health.

I'll recommend this product
if any problem we have help righyt now
many thanks from France

Technical support was great.

This works phenomenally. As an ER nurse I have tested this against our hospital grade equipment and it matches right up. I have recommended this time and time again.

I can monitor my vitals at home. I have multiple heart conditions so the fact that l can monitor my heart rate is the best. It’s a 24 hour holter monitor as well which is convenient in my case instead of going to my cardiologist for them to put a monitor on me l can monitor my own heart and send the results to my cardiologist. It’s the best check me all in one device I’ve ever bought. I have no complaints about it. I give it a 10 out of 10. It’s amazing 🤩

C'est un appareil très complet et qui fonctionne très bien. Juste parfais !!
