Avoid evaluating aspects of the product you have not used or assessed. Avoid guessing an answer simply because the survey requests a rating.
Do not mix a recurring rate with a one-time total. Ask whether the seller provides a clear itemized quotation.
Consider whether you would use the advertised extras often enough to value them. Compare alternatives using the same essential criteria.
