I didn't realize the national purchasing manager read the product reviews (said with the same sarcasim as your post)
Although I am impressed with the product myself, I still haven't posted a review on the Home Depot site, but I certainly don't see a problem with people sharing product experiences as a means to help both the consumer and the company. Regardless, I don't think the reviews are for the benefit of the purchasing manager, but for the consumers seeking information about specific products for needs they have. Of course, I'm sure you already knew that right?
