This is a hard thing for me to say, since I just love the service, when it works.

We have been using Crazy Egg at Asbury for the past few months, and it has been nothing but frustration. We are a fairly well trafficked site, not a google or c|net mind you, but we average in the millions of hits a year, so not too shabby.

I routinely experince time outs when trying to load the results of a given test, even lower trafficed areas that I track, as well as get application errors and timeouts when trying to start or restart tests.

My recommendation to you if you are looking at a service like Crazy Egg for analytics is if you recieve more than 200,000 visits a month, stear clear. They just can't handle the volume of data you will be throwing at it.
