Bests & Worsts Reviews from Amazon

I am a long time Amazon Prime shopper and RARELY have had bad experiences with my purchases until now. I purchased these heated gloves so I could keep my hands warm during ski season. I charged them up per the instructions and then hooked up the batteries to both of the gloves. I followed the instructions to turn on the battery by holding it for several seconds. The batteries lit up. But then, when I went to select my heat control for the glove, nothing happened. I tried multiple times to no avail. Then, I pulled the battery out to see what happened when I tried to select the heat setting. Each time I pressed the button on the glove to turn on the heat setting, the battery turned off. That was the case for both of them. I wasted a good hour dealing with these expensive, malfunctioning gloves, and that's enough for me, so I am returning them. Take heed, folks, as you may want to question the reliability of Amazon reviews. This is the second malfunctioning product in the same week, whereas in the past 5+ years, I can't think of one. Amazon's reviews may be from "verified purchasers" but my suspicion is the sellers, wherever they may come from, are having their friends, family and employee buy their products (probably getting a refund) to post bogus reviews. I've noticed some similar products going to the top of the charts, and the reviews tend to have similar grammatical errors and similar marketing approaches. Seems too coincidental to me. "Amazon's Choice" doesn't mean anything to me any more, which is a shame, as I have been a loyal Amazon Prime customer for as long as I can remember. Amazon, I hope you're listening!!
