Home blood pressure monitors?

[Feek]

Are they any good?

Specifically this, this or this (I get 20% discount on Boots products).

I've heard that upper arm monitors are considered more accurate than wrist, is that true?

It's something I feel I'd like to keep a track of - I appreciate that they probably won't be as accurate as clinically approved devices but it's like anything, as long as they give consistent readings then that's the best that can be expected.

I just bought the first one I linked because it seemed a bargain at around £20 including discount and a friend on Facebook has the same device. My initial reading of 112/58 with a pulse of 53 is pretty much the same as it was when I was last done at the doctor a few weeks ago so I'm happy with that. I don't need it to be precisely accurate but to give me an idea if there are any changes happening that I should be aware of.
