The difference is $7/person. If the tool saves them 10 minutes over the course of a month, it's paid for itself. It's more like paying a construction worker $1

The difference is $7/person. If the tool saves them 10 minutes over the course of a month, it's paid for itself. It's more like paying a construction worker $100 an hour and then giving him a hammer that costs $5 instead of $10, but only drives nails at half the speed because it's too light.
