Sadly we found this item covers such a tiny part of the iglu go up and in our opinion is of little use in keeping rain etc out of pen. The item was supplied with the pen so glad we hadn't paid £14 for the item but as with any free gift one has paid for it indirectly.
I purchased this to keep the Eglu dry when it rains (as sometimes the rain gets in the doorway). I love this product as it is doing exactly what I want and it is a sturdy plastic. Also added bonus of extra shelter from the sun. I can highly recommend this product.
