I'm going through a dry spell on a site due to false reviews having to be removed. My profile on this site should show me at 4.7 stars, but it has me sitting at 4.4 stars. Since this is considered a low rating by some, this has caused my business in that site to tank.
So what should a customer do instead?
Read at least 20 reviews. Even the bad ones then decide if you want to give it a chance. If you are pulled to work with someone or to something research it. More than likely, the negative reviews have no feedback which means they didn't get the answer they wanted or the item wasn't what they thought it would be. If there is a negative feedback read it and decide if you should read between the lines of it.
Always use your judgment.
Blessings!
