Drill straight with a hand drill?

found something new that seems smart. https://www.bullseyebore.com/
Some laser thing. Does it work?

Looks exciting, but personally, I haven't encountered the issue that this solution addresses. When I drill something freehand, it turns out straight enough. If I need to drill something with precision, I use a stationary machine. In short, this gadget has no function for me.

Often when drilling freehand, there is no flat surface to start from.

The question is what the benefit is? If you're putting a hook on the wall, the hole doesn't need to be perfectly straight; it works anyway. If you're making a long hole that needs to come out at a specific spot, it won't be accurate enough to be of any help. Often, when you accidentally drill crooked, it's because the space is tight, and then this gadget likely won't work either.
