We have two GU and they have been good units for the price. I have used them in several Hunt Test weekends with only one problem one day.
But if I was able to go out and purchase more wingers I would probably go with a Zinger as it takes only one hand to load them where with the GU you need two. Also I like the throw better with the Zinger. I do need another winger so I will probably purchase a Zinger with my gift certificate, and Rob has been very good to all the HRC clubs in his area. He provides used Zingers for any club that doesn't have enough equipment to run a good test. He even delivers them for you and picks them up when you are done with your test. Real stand up guy.
