Easy to fit, has an included foam back, and battery lasts pretty much all night .... so it just runs 24 x 7 x 365 days per year. I've had it about 18 months I think and it's still running fine.
But, does it do the job??? Sure it moves hot air out of the observatory on hot days, and you can feel that by placing your hand over the fan, but it doesn't move enough air to do a satisfactory job in my set-up. I'm finding that the observatory is still getting to 10+ over ambient in Melbourne on those hot days which is too hot!!!!, so if I'm home I leave the doors opens which gives a better result.
I'm now looking at a 240v option that will move 250+ CFM and run that on hot days, and hook it up to a Temperature switch .... something like the following:
