I have 2- T2's, 2- Matrix Blinds, & 1-Dark Horse. I had one issue with the Matrix, but it was taken care of promptly.

The new Dark Horse has reinforcing on the rods where I had the problem with one. It seems they are looking to fix any issue they might have encountered.

Over all DB's have performed flawlessly!! I have owned 4 different brands of ground blinds, but all I own currently for my own personal use are Double Bulls.

They are heads above anything else out there in features and overall Durability.
