Phew – my NR90AD is safe. I do think the box stores get ‘special’ models, I think special means cheapened.
I used to work for a food company when I was young that got in with Costco – worst thing that ever happened to them, pressure to get the prices lower and lower and before you know it they were pushed out of business all together. When they couldn’t get the price low enough after doing everything they could to get the product down lower in price – by that time they needed the big volume to survive and when it went away, so did they.
Model ABC tool at HD will be the exact same as the same model number at the specialty tool store. Now, if there is model ABC-1 and ABC-2 those will be two different tools.
