One problem I have found with Amazon is when a buyer has a question about an item, Amazon provides a “Ask the community” section which I have used frequently and you would not believe some the answers you get back. Some have nothing to do with your original question and others are totally opposite of reality.
Amazon should require that sellers only can answer these questions and that alone would reduce returns.
We ordered: Nest Learning Thermostat, Easy Temperature Control for Every Room in Your House
We received The Nest Box. Inside we found a wad of dried clay instead of the Unit! Somewhere in delivery, someone stole this $219.95 device and replaced it with an equal weight of clay. The box appeared perfectly sealed.
We returned the clay for a refund.
