Why wouldn't a woman appreciate a tool that will make her job/work easier, like a $300 vacuum cleaner. If my wife bought me a new $300 tool, I would not complain.
Just saying.......
If that $300 tool was for daily or weekly maintenance that you were just expected to do, that should have come out of general expenses, and she burned up one of your gifts for you on it. I think you might have an attitude as well. My opinion
