I worked at place that got negative reviews and got sued also and lost. They are still in business. So I say that is not true. If you think this way, you should not be facing any customers, because your ego can’t deal with a bad reaction.
You are putting onus on the reviewer, not yourself. You blame the reviewer, not what is made. I worked in QC/QA for a long time so I know about commercial products.
Just because a review is negative, does not mean it isn't deserved.
@botrytis While I agree with most of this, your statement about what I'm doing or how I deal with customers isn't correct nor does it describe who I am.
Most of the negative reviews I've read that were undeserved were not about my products. For example (one I've already given), Gryphon: the reviewer wanted them to give him a very expensive set of amps. When they didn't, he published a negative review. I was there in the room at CES when he threatened them.
Again though, your last statement is not what I was talking about.
