I assumed that the price of this speedometer came with tradeoffs, but I have found none yet. It is easy to install, accurate (within + or - 1 mph of all speed signs I have passed), and functional. I recommend spending some time learning how to scroll through the functions and reset them before riding. I assume this would have alleviated the reviews that people wrote about the interface not being intuitive; I think it fair to say that those individuals associate "new and unfamiliar" with "not intuitive," which is unfair to Schwinn.
