This is by far the most accurate watch for counting the total calories burned. The Apple Watch simply did not let me view the TOTAL calories burned, as it would show your estimated basal metabolic rate and then stack the active expenditure in a separate category, so you’d have to go back and forth to view each one and then add it up. The Galaxy watch suffered a similar problem, but it was not that accurate at measuring steps, which would directly affect the caloric expenditure. The FitBit was just WILDLY inaccurate and once told me I burned 5000+ calories in a day because I had a panic episode after something bad happened in my personal life, and so that night it registered me as having burned thousands of calories just laying in bed.
The Garmin, however, did everything right (accurate steps that match the ones my iPhone said to within 5%, heart rate matched a professional blood pressure cuff, and the calorie counter tracked my weight loss exactly). It is extremely useful when counting calories where a slim margin is needed, such as aiming to lose 750 calories a day to lose 1.5 lbs/week. It it’s off by just 100 or 200, that’s already a half pound off, or 26 pounds a year.
It is extremely important to me that it gets it right. It also has a ton of features, but I don’t use them honestly. It’s very easy to connect and set up, too. The price is subjectively fair but objectively it is quite high. Regardless, I am very pleased with it. The battery life is EXCELLENT if you turn Bluetooth and WiFi off, too. 5/5 all around!
