i just bought one a few weeks ago. they are very nice! ive used it once already and killed a bird out of it! the floor zips in and out. i havent used it, but it seems like it would be kinda loud. it is made of a heavy nylon material. again i havent used it though, so i dont know for sure. the shoot thru mesh zips in and out or you can unzip it and use the bungee style hooks to hold it up. the windows have strong magnets to hold them up, but they stay put well just being behind the rods. for the money, i would sure recommend you get one.
good luck
