I had a issue with a unit. They kept in contact with me till a new one was delivered. This company is all about customer service! I will be recommending them. Thanks for everything.

Seit zwei Jahren begeistern mich die exakten Messergebnisse des O2Ring-S. Von meinem Pneumologen bestätigt. Leider beendet ein Systemfehler die Funktion. Aber mit dem Serviceteam wurde sehr schnell eine Kundenorientierte Lösung gefunden mit der ich sehr zufrieden bin. Vielen Dank, Einfach super gelaufen.

This Ring 02 monitor is precise and convenient. it is also trusted by the medical community. I used the pulse oximeter technology for over 40 years as a Respiratory Care Practitioner so I know the technology is reliable. I'm so impressed by this device and the reports that are generated daily truly assist in diagnostic use. I send the reports to my doctor when I'm having problems which provides a basis for other testing

I needed a real time measurement device. A search found this device, so I ordered one. After using a few times, have been very pleased.

The Smart O2 ring is a great help in my revalidation therapy for lung fibrosis. To bad the ring was defective but their excellent customer service send me a new Smart ring without any problems. This ring warns me with vibrations if my oxygen level is to low or my heart rate to high. And in some cases my phone must be on silence so that function is great. Futhermore it helps me to get more inside information what excersises ask to much energie from me, even when I use extra oxygen via an oxygen concentrator. Yes I'm very pleased with this Smart ring

I bought a pneumatic leg compression device. Unfortunately, the controller didn't work right from the start. I was worried, but as soon as I contacted support at getwellue, the handling of the complaint was super easy. I didn't even have the hassle of returning the bulky pack and got a complete new unit sent. The new controller worked and I also must comment that the boots, zipper and cabling of the leg compressiin boots are all well made. Compression is very strong, I use it on the lowest level for lymphatic drainage. I also love the fact that it can be used on both the batteries and on 240V.

The ER1 LW is well-suited for long-term ECG and heart rhythm monitoring. The AI analysis has been very helpful in monitoring my PAC, PVC, and VT. It's a great product for people with arrhythmias. I don't know yet about its durability, but the fine texture suggests it should be durable. The manufacturer's service is excellent; they were willing to replace the wrong patch (which I bought for the ER1) with a new, suitable one, making me very satisfied. The BP2 can monitor blood pressure and perform a 30-second ECG. It's small and easy to carry for travel. I hope it will also be durable. I would recommend this company's ER1 and BP2 products.
