Works well for letting in light for our rabbits but a couple of design points: it does build up condensation; not big enough - could be bigger to protect side against rain; traps flies inside - would be good to have a fly net a well maybe??
I wish this cover was just a little wider, ie came right down to the bottom of the run. It keeps rain off a strip down the centre of the run which is better than nothing but rain runs down the side of the cover and wets the outer edges a good 6 inches into the run.
Looks good and I can still see Gert& Daisy inside.
