I've used them for years and they rock. So roomy and break that cold wind. I use the Doghouse. Why? Because it is light and does not have hubs that break. Repeat -- hubs that break. I have experience with three hub types and they all broke quickly. I actually have two Doghouses and set them up side by side when hunting with a pard. A word to the wise: if you hunt with them, practice in them. I found that the right chair makes all the difference. Typical camp chairs are too deep for archery. stools and tripod stools SUCK after the first 20 minutes. The advantage to a ground blind is you can hang out all day with ease. Read a book, make a sandwich, whatever. I don't put the mesh up, just open the windows and get in the dark spot. Love 'em.
What chair do you suggest? I've been using a canvas camp chair, but like you said too deep. I'm thinking some director's chairs might be better.
