There is .3 of an inch difference in the Touch and the Glo height wise which I find makes the cases incompatible long term. I am getting by for now with a losely fitting Touch case but I would rather a better fit. Since the official Kobo Touch case is quite a bit larger than the device and it has pretty losely fitting elastics the Glo slips out of it way too easy and it's bulky to travel with. A half decent fridge magnet stuck into the pocket of the case where it meets the bottom right of the device has added the sleep function.
I really wish Kobo would have educated the sales staff at their partners about this. In my hunt for the sleep cover I have been told endless times that the Touch cases work fine for the Glo. I had to pull mine out and show them the difference.
At this point the Glo cases remain AWOL in Canada with no shipping date known. I have decided to order a cheap case from ebay that looks snug enough to do the job.
