I have the older version of it ... when it was made and sold by Otter Outdoors. It works very well, though you need to carry a large sponge if you're getting in and out of it in water, because your waders will bring in a lot of water during the process. I put 4 I bolts where they're shown in the pic. with fender washers underneath, to help support the blind if I hunted in water deep enough that the blind had to float. I made 4 poles out of 1/2" conduit, with I bolts near the top. I'd take a half hitch around the poles at the blind level and tie them off at the I bolt in the pole.
To keep the weight off the I bolts in the blind, I ran the ropes under the blind, and fastened the two halves with a gated link. You can tie the ropes together, but they drag in vegetation. Using the link allows the ropes to be loaded into the blind and the blind will slide easier over vegetation.
The only real criticism of it is that, being square sided, you need some camo to blend the angles into the surface. The blind they sell for it does that, but you can do the same with a larger piece of camo burlap, laid over you like a blanket.
