Not and have any idea how close I am to my target deficit; I'd either err low and fail to lose the weight, or err high and badly endanger my health via malnutrition. With the band, I know exactly where I'm coming in on a daily basis, and I can, for example, plot calorie deficit over delta-weight and see where I should be aiming for best effect.

In general, I'm surprised to see such a Luddite attitude espoused on HN. What kind of engineer doesn't see the value in collecting the necessary data to characterize a problem or a process accurately? That's Step One.

Yeah, I love to collect data on my running, for example. But my point is I'd (and probably you would also) be doing it anyway, with or without the data.

The basis band you mention looks pretty cool though, going to check that out further.
