### ⭐⭐⭐⭐⭐ A must buy, to get the size for this brand
*by L***. on 12 May 2026*

More expensive than other makes, but it does make a difference, so glad I bought these and didn't go by another make that someone let me borrow I would have been a size to small! I kept it on for the 24 hours, and when the ring came it was just the same
