@coercri.....Some time ago I bought the "Vipertek" case which appears identical to the one jon described only different name. I published my comments and pictures on another thread in this forum. I think the same design case has popped up on Amazon over last months all about the same price with different names. It's still working well for me and holds the tab really well no matter which orientation you use. I have copied my original post including photos and attach it for your information.
The link posted by azoller1 in reply to my original post is the correct link to Amaz. Ordered it on 11/12/11 and it arrived by USPS on 11/16/11. It looks, it feels and it smells like leather on the outside whilst the inner lining is micro-fill. It has 6 "clips", (looking at it in landscape view) 2 are at the top L & R corners, 2 are at the bottom L & R corners and the final 2 are on the L & R sides about one third of the way down from the top. When it is closed up the A500 engages in all 6 clips. When it is fully closed every "input" (power,hdmi,usb full, usb "B", on/off button, volume up/down, rotation lock and even the sd card cover) are all accessible. To operate the A500 you have to "unhook" the bottom 2 clips and slide the bottom edge of the A500 into one of the "ridges" where it rests at the required angle. Although I am not an acomplished photographer I hope the attached photos will show that.
Having used it for a couple of days I am growing to like it especially at the price I paid.......THERE LIES THE RUB!......... When I bought it on 11/12/11 it was quoted on Amaz's site as $9.93 plus $4.99 shipping and even without seeing it I thought I couldn't go wrong at that price. On Tuesday 11/15/11 I went to Amaz's to check on delivery date and ........SHOCK HORROR........ found that the price was now shown as $19.98 plus shipping. Long story short I checked my bank account and found that the original price quoted me of $9.93 plus shipping was what had been charged to my debit card. There was no notice on the web site when I bought it that it was a special offer or some such so I can only conclude that for a short time a mistake had been made by the selling company.
At the price I paid I would heartily recommend this case BUT I am not certain I would at twice the price. But if you like the look of it, look around and see if you can find a reduced price.
