Omron Sphygmomanometer, Black, Large Adult Best Quality

Two major complaints:
1. The Amazon ad for the sphygmomanometer in no place gives the actual size in inches of the cuff. I took the word "large" at its face value (to me); the ad should probably have read "giant."
2. Amazon's return policy says the item has to be returned "unopened." How stupid it that!

Needless to say, I won't be buying anything more on Amazon if I am not completely, positively, fully, infallibly sure that I won't be returning it.

Amazon, get real!
