You have the feddbacks of real people who purchased the products and services of David P. Montesanti, MD (Ophthalmologist) in the territory of Niagara-on-the-Lake (Canada).
Right now this firm has a rating of 4.9 out of 5 and that rating was based on 91 reviews.
You must have seen that its rating is almost the best one, and it is founded on a very large number of scores, so we may be quite sure that the assessment is very faithful. If people have bothered to give their score when they've done well, it works.
As you know, we don't usually bother to write tatings when these are correct and we usually do it only if we have had a problem or issue...
