好像是戴在手臂上的那种，很方便的。用英语怎么说呀？
谢谢！

我在ebay买过一个，孝敬老爸的，运费后$35。好像叫wrist blood pressure meter吧，自己查查吧。

thanks

I bought two before, and the sales told the wrist pressure measure is not as accurate as the upper arm one. But the wrist is smaller and cute.

correct,the arm one is much better

any detail?

是真的，不很准。其实用医用的很简单，你真想买，我可以教你怎么用的
