If I am trying to find the best item to buy, I will rely first on Amazon reviews (one star and two star reviews pointing out flaws in the product), and maybe Consumer Reports. Consumer Reports is not as useful as it used to be. It only lists a few items of each type, and lists them in a brief chart that does not really tell you very much. The older Consumer Reports magazines would devote a few pages to reviewing the items in more detail. Other than for automobiles, Consumer Reports now devotes the longer multi-page reviews to consumer issues, rather than consumer hard goods. I bought a Mr. Coffee K-Cup coffee maker on sale in Walmart, and it stopped working after a couple of months. I read all the reviews for K-Cup machines on Amazon, and finally decided to give up on K-Cup machines completely, as they all seem to be junk. To make coffee, I am presently using up my supply of K-Cups by emptying them into a pot of boiling water (1 K-Cup per quart of water). I remove the boiling pot of water from the heat, empty in the K-Cups, stir for a few minutes, let the coffee settle, then pour it through a filter and filter holder into a stainless steel water pitcher. When the pitcher cools, I cover the top with plastic wrap and a rubber band, and put it in the refrigerator for use over the next few days. So I found the Amazon one star and two star reviews to be very helpful. They saved me from wasting more money on K-Cup machines. You can't do that by looking at them on a store shelf.
I also have a retirement hobby of writing Amazon reviews, and I recently received emails from companies wanting to put together a stable of Amazon review writers. One company was even willing to pay for the reviews of free products. I told them no thank you, for many reasons. I am not looking to start up a paying business. I don't want to deal with any of their rules and conditions. I don't like other people making rules for me to follow, I prefer to make my own. I don't want a houseful of free junk that I can't use. I am not even willing to pay the postage on these free items listed on Amazon, under Amazon's new coupon code system. I have no desire to subscribe to the Amazon Prime "free" shipping program. And last, but not least, how impartial can a review be when you are getting paid to write it, or being told what to write and how to write it? I can think of a few other reasons, but as Frank Sinatra said in the famous song, I did it my way, and on my own.
