I don't have the big mike model but I have the Barronett grounder 350 and 250 made by the same people. the 350 is just a little smaller but it has tons of room. I just bought mine this fall and love them. Of course it helped that I arrowed a deer and a turkey first set. They go up and down easy and are stable in the wind if you stake out the tag lines. I still have one out now thats been snowed on and freezing rain no problems. The premos chair is a bit low for the windows on the 350 but you can stand in it. I'm 6' no problems. The 250 is smaller and the windows work fine with the premos seat. The quality is good. Best was the price, I gave $99 for the 350 and $80 for the 250 on sale at an orchlin farm store.
