Overall: The disparaging reviews on here are very short sight. Does exactly what it says on the tin. I think some people think this is supposed to their training for them.
Yes it is not instantly intuitive but it is highly effective when used correctly. Of course the 610 is better, it is 3 years younger.
I have had 405 since its release and it has served me very well. I haven't felt the need to upgrade to 405 as they offer the same features. 610 offers 4 fields instead of 405 3 fields and it offers 'training effect'. Other than that the 405 will serve fine. Especially for those on a budget.
