Lesmart High Impact Plastic Golf Ball Tray

It is well designed and the photo is representative. My only concern is the longevity because it's made of hard, brittle, plastic, as opposed to rubber. I am concerned it will eventually crack, but so far so good. I would also say that 100 balls would be a bit of a stretch capacity-wise, unless you very carefully placed them to make it happen (though I admit I have never tried to put in more than about 60).

I use this in conjunction with the Galileo net and the cage I built out of PVC - holds approx. 89True flight or regular golf balls and keeps them handy next to my practice mat. Works very well - easy to rake the balls out of the tray with an iIron or wood and on to the mat surface - balls funnel down toward a central point as you use them down. I did put a bit of gorilla tape under the front edges to keep it from moving around so much on my concrete garage floor and golf training area!
Do keep in mind that if you have pups, they will love to chew the Tru-flight balls - so you should put them in a bag when not in use, or at least up off the floor.
