I don’t have an issue with the sizer but it took two weeks to arrive. Then, when I was ready to purchase a ring, there’s a big “20% off your first purchase” pop up so I signed up for this and when I was ready to purchase and put in the code, it didn’t work and I was being charged full price. I emailed the company to ask what went wrong and after two days, they finally replied that the 20% off was not good for the purchase of the smart rings. Very misleading. I ended up purchasing from a competitor.
