Well really i want to say 'thanks' for putting your product out there for so many of us to try -- yes, I agree, a week in one's typical working life is not really enough to get a handle on all the nuances of a product but I hope you found the exercise useful also. Not clear how we could improve the process, giving everyone a month would make the process extremely lengthy, circulating more than one test set at a time would perhaps be unreasonable for the manufacturer, but I have to say, I love this kind of direct user input.
