Earlier on, I was browsing Amazon to find a generic case that was a close-enough fit for the KA1 since Kobo's was out, and frankly too expensive for what it is (they're not Apple... not that I'd buy their accessories either

)
And I came across
this one.
Even though it's fairly generic, listed for some (smaller) Kobos among many, the KA1 is not mentioned. However as you can see from the attached pics, it's a perfect fit sizewise. I ended up trimming the bottom tabs a bit, and they still protrude a bit into the screen corners but since there's never any text there, I don't mind.
I like it because it's a bit rougher, though it is fairly smooth and simple compared to their other offerings... It's pretty stiff and a little bent, so it offers plenty of protection for the screen. It makes for a nice contrast with the hi-tech device inside. You can use the latch with the cover folded over, and it also stands up too if you fold it halfway.
No need to special order either (it's Amazon), though I had to return the first one because it had blemish that was way too big to overlook :/
Now here's my question: it doesn't have a sleep function, and with the KA1 power button in the back it's not ideal. I'd like to see if I can make it work, tried with some weak magnets, no success. Does anybody have the info where the sleep/magnet sensor is located exactly on the KA1's frame? (I can always try with stronger magnets)
