Garmin ECG capable watch

Does anyone use a Garmin watch with ECG app? I currently have a Garmin instinct that I use for sports. I also have a Kardia device to take a ecg rhythm strip if I feel that I am in afib. I am thinking of getting one of the Garmin watches that have the ECG app but since they are very expensive I was hoping to get a review from an actual user. I don't go with an apple watch because the Garmin has a battery that can last about 30 days which is very helpful if you are doing any long distance hiking or traveling. Any Garmin ECG users here? Thanks
