Hi Pufflemum. I guess you mean the Outwell Birdland? I've never heard of it before but googled and found reviews and users' photos on ukcampsite.co.uk. There are loads of positive reviews and photos for the Icarus too.
I wish I had bough a Vango Icarus as my easy-to-put-up tent instead of a Decathlon pop-up, which is v fab, but does not have a SIG in the porch area. Last summer's endless rain led to slugs in my cooking crate .
