Hey there. I bought the STM Stash bag to protect my iPad when it's out and about. I also have a cover on my iPad. It's a snug fit, and I have to put some pressure on the screen and the aluminium back and pull quite hard to get my iPad out the bag. Could that cause a problem or damage? My friend has an iPad with a magnetic case, and he tried it on my iPad. Since it's a magnetic case, could the magnet damage my iPad? Also, my STM Stash is 'water resistant'. If I was caught in a heavy downpour, would that seep through? I was out in drizzle today and was concerned.
