Lol, well the size of my yard wouldn't justify it. I've got a half acre but my yard is ~5,500 sq ft. Much of my lot is old growth woods. I just like toys and justify it by not paying for professional lawn care and occasional pest control. I definitely want the sprayer to be strong enough to reach the eaves of my roof for carpenter bee treatment. Also, as mentioned the consistency is great with battery backpack sprayers and I try to follow calculations pretty closely for most things so I am also taking that into account.
