These tools are for those baristi that wish to re-create the same dose every time, or to be able to adjust the dose incrementally to experiment. These are tools. I can use a framing hammer to drive stakes, and a sledgehammer to drive brads, or a rock to drive roofing nails. If I want to be really satisfied with the results and get the job done quickly and well, I'll use the appropriate tool for the job.
Some of you have tack hammers, but it's 'cause you're driving tacks. Some of you have rocks, but it's because you're driving wooden stakes. These 'hammers' are for driving specific 'nails'. To suggest that they are useless just because you have no use for them is a bit presumptuous.
