I've had a double for about 12 years, bought from Bushwear and will shortly buy another. I would always recommend a double as it's great to have somewhere to put your bits: spotter, spare ammo, binoculars, book, occasional dog. The cup holders are pointless though. I've never had any issues with the magnets holding the window screens but there is no doubt that there should be a screen covering the front opening. There is no alternative but to fit your own as quarry often turns up way too close for you to breathe and the last thing you want is to be wearing full camo inside the hide. Over the years the light is shining in through pin pricks from various encounters with holly and brambles but the fabric has never torn. It's pretty rain proof. Again, over the years it has sheared the bolts allowing the cover to fold out, but they can be replaced relatively easily. Mine has been permanently outside for the last five years, pegged down with ground screws, and finally the seats are getting a bit delicate. They are quite small for the size of my arse at 6'2", but I always carry a foam seat to avoid blood loss. Getting a tripod in is ok so long as one of the legs is threaded under and between the seats. I don't think you can find better.
