At first the device worked The ordered device worked at first, but later it had problems. The computer program did not recognize it. I sent a video about the problem and corresponded with the company, who helped me, first with advice and then with a replacement device. Thank you very much for your help. I have had a heart rhythm problem since I was 12 years old, I had 3 surgeries. The device and your help means a lot to me.

I can sleep now Received product promptly. Easy to connect to app. Made my life so much easier. Was staying awake or waking up multiple times a night to check my husband's O2 because of his sleep apnea. Now I can set parameters and my phone will alert me if he goes below parameters. I can finally sleep. The app gives a very nice printout. I do have concerns about the thinness of the material that transmits the data and how durable it will prove to be. Time will tell. Highly recommend.

ECG Recorder with AI Analysis - great! I purchased ECG Recorder with AI Analysis. Great device. Very comfortable to wear (I am using belt), sometimes detects a few anomalities at the very beginning of the measurement, but then settles and seems fine. Very good to check on your heart. As a bonus it behaves as a bluetooth heart rate belt, so you can send BPMs to your Garmin or Karoo when cycling & still capture the whole ECG into the device at the same time (and analyse later).

Good but please make it IP68 !!! Hi, It works, no problem. I'm dreaming of an oximeter that can be used under water for freediving training. The perfect one could also be post synchronised with Garmin connect as an external data field. We are thousands of free divers seeking for this product... best

Extraordinary products. I’ve bought two different AI ECG products from Wellue and every aspect of the sale was smooth and efficient. I can’t speak too highly of this company. They have been excellent. And both products have performed beyond my expectations in every way. I believe that anyone with a heart arrhythmia such as atrial fibrillation will benefit from using these well-priced and technologically advanced AI devices.
