Anyone use a BuckStumper blind?

[BlackBelt]

I've seen those BuckStumper blinds from G&H Decoys advertised. A buddy of mine and I were thinking about getting one and trying it out.
If you haven't seen it, it looks exactly like a big tree stump, and you put foliage up around it and sit in the middle of it.
Just wondering if anyone here's used one and what they thought about it.
Thanks
