My husband and I think it's good. It's actually a wrist type. To be precise, this one.

We also have a more expensive traditional arm cuff type (with the squeeze ball), but it seems less reliable/accurate than the wrist type. My nephrologist wanted me to buy yet another that he recommends, but in the middle of a chaotic home improvement project and upcoming move, a third one just seems too much. It's a shame that so many doctors are not seeing patients face-to-face. Of course I understand, but healthcare is suffering a lot because of it.
