I just got this Blurex case
(I figured an android tablet needed to be in a green case :-). It came with not only the case, but a screen protector (which I probably won't use) and an OTG cable. It is yet another version of the similar case from Moko and YooMee. The magnet in this one finally appears to be exactly the right strength, turning it on and off reliably, but not turning it off when I fold the cover back. It has the nice elastic strap to hold the cover open and the wide strap for slipping your hand under to hold it. I think this is the best version of this case so far.
