I was one of those shooters on the fence about purchasing a MagnetoSpeed chrono, but after reading numerous reviews / watching some videos and hearing recommendations from other shooters I decided to get one.  This is my first Chronograph and what really sold me was the simplicity of the whole package.  I am very happy with my purchase and would definitely recommend this to a friend that was in the market for a chronograph.  One of my concerns was the fact that I have a muzzle break, but it proved to not be an issue at all as all shots that were fired registered.  I used it on the bench and prone without issue.
