I never thought much about oyster sauce.  I just bought whatever was available thinking it was all the same but the last two times I did that, I regretted it.  They were two different brands but both were cloyingly sweet and basically inedible.  Annoyed that I had ruined two potentially good dinners, I turned to Amazon to restore my faith.  After reading reviews of several versions of oyster sauce, I decided to buy this one.  It was the best decision I've made in a while.  This sauce is delicious and tonight we enjoyed a very tasty Beef and Broccoli in Oyster Sauce.
