Smart Ring ที่ดีกว่า อึดกว่า และถูกกว่า : Luna Ring Gen 2

Last time I reviewed the Smart Ring and mentioned two major advantages over smartwatches, but the measurements weren't very accurate. This time, I have my second Smart Ring, the Luna Ring Gen2. I've tested it and can say it's more accurate, has better battery life, and is cheaper. Does it have any drawbacks? How is it different from Ultrahuman?
