I did purchasing for a jan-san distributor for a few years, look for the name UNGER I bet you'll find them on-line. Their grabber is well made. All their stuff is.
My wife and I do clean up... on dry land. Blew out one grabber recently after, eh, six years. Just got another at the Infamous Harbor Freight Tools store, dirt cheap and I'll consider it expendable.
