Customer reviews are an excellent source of feedback. The more information given by the reviewer, the better.
For instance, a review which says “great service, can’t wait to use again” is a nice pat on the back, but may not tell you much about the process.
However, a review like this gives you helpful, specific information:
Mark West is a top notch, cream of the crop kind of person. I'm so glad I reached out to him when I needed to refinance my home. I had sooooo many questions and he patiently answered every one of them promptly. I kept texting him asking him what about this? What about that? I apologized for asking so many questions and he replied with kind patience and answered all of my questions. I will recommend Mark to ALL of my friends, family, and my own clients from my business. I appreciate him. 5/2020
Pro tip: Look for longer, more detailed reviews for insight into the customer experience.
