Modulation is everything. That is the idea behind the Core CO2 inflator. The dial regulator allows you to crack a cartridge to get just enough CO2 into your tube/tire to get it to take shape and allow you to make sure everything is seated properly. Once you know you are good to go, open the valve all the way and let er rip. The minimal design is everything you need, and nothing you don’t.
