Now I can practice chipping over their car as I am avoiding a large bunker and not have fears of breaking a window

Inside, outside, I know they won't break my windows if I have a wayward hit, and I love that I can practice my swing inside when the weather sucks.

I have a small back yard, so these foam balls allow a medium swing and contact without reaching and breaking my neighbors windows.

In regards to the multiple questions on behalf of possibly breaking windows

Soft so they won’t break windows

his 1st BB gun he shot & broke our window and accidentally shot our car

I wanted a practice ball that would NOT sail over the back fence and break the neighbors' window.
