Nowadays the firm receives a score of 3.9 stars out of 5 and the score is based on 15 reviews.
As you can read, its rating is quite high, and it's based on a very large number of opinions, so we can conclude that the assessment is very credible. If people have bothered to give their score when they've done well, is that it works.
You know that we do not usually bother to place scores when these are positive and we usually do it only if we have had a problem or issue...
