Yes, of course, there's more steps involved than just closing the cover... but then, just closing the covers isn't much less work than briefly sliding the slider over and then closing the cover. So I'm not really bothered about the magnets either way.
The magnet does seem a bit gimmicky, doesn't it?. Using the slider is pretty easy. Does the magnet also keep the cover closed without a tab or elastic band? Some of the photos of sleepcovers have closures and some don't.
