APPLY THE WRIST CUFF - Remove any cloth that covers your wrist. If you roll up your sleeve, do not roll up too tightly, that may constrict the blood flow in your arm. Wrap the wrist band around your left wrist firmly, leaving 1-2cm between the cuff and the bottom on your palm. The monitor screen should face the same direction as your palm does.

After going through quite a few options, decided to go for this one as it was the least expensive one in the market. Seems to be working fine. Build quality is decent, doesn't feel cheap. Following the instructions given in the box carefully, gives a more or less stable reading but not sure how accurate it is. But I am guessing the error probability is around +/- 5 units which is acceptable. One improvement could be to include an optional backlight in the display for better visibility. 1 year warranty is a good benefit. However, you need to register the product after receiving it via a Google form link, which I did but I did not receive any confirmation that the warranty has been activated.
