Good smart ring.
This ring works great for me! It measures my blood pressure, records my sleep pattern along with my blood oxygen saturation and heart rate. From a smart watch I had, I know I walk 3 to 5 miles a day where I work. I have not noticed step count on this ring. For the price, I find it to be a great purchase. I would love it if it showed the time of day.

P.O.S.
It took over a month for this product to be shipped. When I received it the return window closed in a week. By the time I used the product and found out that it was a piece of junk my window was already closed to return. Don't waste your money and don't waste your time on this product.

No blood pressure measurement
It doesn't measure blood pressure. It has some other odd measurements. The sleep measurement is useless. It always says my sleep is great regardless of how many hours I get or how many times I wake up through the night

Overall okay
It works well enough. The blood pressure is way off but the rest works okay. For the price you can hardly go wrong.

Not worth it
While it worked fine thw first day or so, it did not accurately take readings, and it stopped working completely after 3 days.
