Folding reacher grabbers can provide convenience for traveling and other situations where having a folding reacher grabber tool means bringing a reacher at all.
One thing to make sure of is that your folding reacher grabber tool has a hinge that locks. Otherwise the folding reacher tool may not be effective at picking up heavier items off the ground.
My experience with folding reacher grabbers has been good, although if convenience is not an issue then a non-folding reacher tool might be a better option.
Lastly, you might find it convenient to carry a folding reacher grabber tool on your person if you want to have one with you all the time. The shorter ones can work well for this since when folded they might only be a foot long.
