Some reviews online are great and authentic... Some are obviously paid for...there must be a company you can hire to give your product rave reviews!
A 'Gourmet' strawberry jam online from a well-known retailer... It got several - maybe four - 5 star glowing reviews. OMG. WTF? Was I wrong in expecting some flavour? Other than sugar? And a couple of gelatinous membranes of a part of a couple of actual strawberries? Still stymied and well, I feel cheated.
Reviews are a big part of life these days! Marketing...merchandising...and most of all...you the consumer. We count on them to make decisions! So it's only right that they s/b fair.
