They work really well! As you can see in the photo, where you catch the eye, it is very visible. When the ball is first hit, the impact mark will be light and then darker. They work best on grass. I have a lawn with a "bump" in the middle. If you get hit there, as you can see on the 6i and 5i, the "grass" will smudge the hit sticker and some of your hits may be obscured. However, they work exactly as described, come off very easily and are rated for 5-7 hits.
