I know that Tracy has had good luck with the 350, and you can't deny that. I have know him through this site for a few years and I value his opinion.
However, I bought two grounder 350 blinds and they both were junk. both of them broke either rods or hubs the first time I set them up. I received replacement parts a total of 4 times, I finally gave up and returned them. I may have gotten two lemons, but I would not by a third to find out.
I do however, have a snake eyes 375, from them that is a great blind. I also have a double bull recurve and a Primos vision, that have been good blinds as well.
A blind is a great hunting tool, Good luck!
