It's a larger, more robust version of the mini button trigger sprayer. Its defining features are:
Button Actuation: It is activated by pressing a large button with your thumb or fingers, rather than squeezing a full lever. This requires less hand strength.
"Big" Design: It has a larger pump chamber, a longer dip tube, and is designed to fit on larger bottles (typically 1-liter / 1-quart or more).
High-Output: It delivers a higher volume of liquid per spray compared to mini sprayers.
It's the go-to choice when you need to cover larger surfaces efficiently without the fatigue of a traditional lever trigger.
