Great value
I’m really happy with this purchase! The ring sizer is very easy to use and gave me accurate results within minutes. It’s straightforward, no fuss, and perfect for figuring out ring sizes at home. For the price, it’s excellent value—definitely worth it if you’re shopping for rings online or planning a surprise gift.

Correct size-ometer
Love the fact you get 2 one that shows letters and then one that shows numbers, great for travelling. Only downside is the table with all the measurements has very small writing nearly need a magnifying 🔎

Good but not reliable
Very easy to use and comes with a lot of guidance and information. However seems difficult to get an accurate reading when trying to consider knuckles, when you move the sizer around your finger, the arrow is easily pushed to a different size, making it hard to know which size would fit properly. Still is very cheap and worth buying to get a rough guide.
