I mostly use the grabber to pick things up with, not so much for things on upper shelves, with my luck, it will drop out of the grabber and hit my toe, (has happened,) I'll just use the step latter for things on the shelf.
Because of my back, often when I drop something on the floor, it stays there unless my grabber is nearby. When friends and family used to visit, they used to complain about all the change scattered all over the place a dime here, quarter there, I wasn't about to bend, for loose change unless it came time I was desperate for money. You should see my face when I'm out shopping at any store and I drop something, I darn near want to cry, it's quite the production if I have to pick it up without causing a great deal of pain to my back. Sounds like a good idea to bring the grabber along, but, then, that's just one more thing I'll have to try to remember to carry and likely leave behind at the store. Sigh
