Most sales folk and/or courses place it where an unhappy person mentions it to about 9-12 people, where a really happy person only mentions it to about 3 people.
That said, I feel that the internet has changed that game being it is now a LOT easier to get your feelings out to a much bigger group of people than previously possible post internet.

Still ..... B.H's reputation and the shear volume of negative comments about them, and what sounds like a total disregard to customer satisfaction is enough to put me off dealing with them, which is a shame, as I REALLY like the look of their newer 6-8ch 1600mm wide foamie war bird range. That guy Pete they stick on their videos is also another factor that puts me off, as I personally find there to be a total lack of an honest opinion on his behalf ..... I mean, how many times can one person state that they have "a beautiful, beautiful plane" every single time they pop up online!?!? - some are nice looking, but not all of them

Might just stick with looking at the locally imported FMS large foamies I think - least they work!
