Dollar Tree has some grabber's for $ 1.00 of course. They cannot lift cans but they can grasp lighter objects. I haven't measured mine but, I think it adds about 2 ft. to my reach.
I also buy their backscratchers - they are curved at one end and great for manipulating golf balls-& also herding them through chain link when you are afraid your pudgy wrist will get stuck in the fencing. Okay, so I mean my wrist. I did once(at least) get my wrist stuck in the fencing and decided if any one came along, with my other hand I could throw my wallet over the fence (8 ft.high) and say I was trying to get my wallet back. I haven't decided how to explain a wallet flying over an 8 ft. fence.
Funny now not so much when it happens.
