I was reading through the reviews and then noticed that retired engineer had posted this:
A little over a decade ago, I bought my 55 gallon drum of lube. I never thought I'd use it all but a few days ago the pump finally ran dry. I've had a lot of good times with it. My wife, too. And not just what you'd think. One day I just hosed down our hardwood-floored hallway so I could use it as a slip-n-slide. You shouldn't think of this as a 'purchase.' It's an 'investment.' An investment sure to pay off in spades.
