Query: OMRON REVIEW

Hi,This Omron BP monitor is showing incorrect results. When compared with Mercury BP monitor there is difference of around 30. This means this instrument is showing reading 30 more than mercury monitor.I am disappointed with this BP monitor as this is not going to serve the purpose for which I bought.Unfortunately I have travelled out of United States otherwise I could have returned this instrument instantly.RegardsDeepak
