Question: Has anyone had any problems with background marks after they put the plastic screen cover on their iPad. I took mine into apple to see what the marks
Document: It would be a decent cover IF it put the IPad to "sleep" like the basic cover from Apple does. I will be going back to another cover I found at Best Buy that is more of a soft version of this that covers the screen enough to trigger an automatic shut-off.
The iPad will sit inside a plastic holder (as you see i the picture) but isn't snapped in or secured so it wont hold it if your moving it around. Should have realized from the picture that hte apple icon is showing and is on the back of the iPad not the front which also seemed odd when I opened it. I don't use this and didn't cost enough to warrant the postage to return it or I would have.
I bought this (the black one) as it was extremely cheap and my Hubby wanted me to remove my pink cover:-). It is really good, nice and I like it better than expensive one that I bought at Apple store as with this one my Ipad stands without any problems. Really really good and nice cover.
This cover is nice, especially for the price. It swivels via the circle that highlights the apple log so that you can use the ipad horizontally or vertically which is great. It does feel cheap though and mine came with a crease in the cover of it. It is not bad enough for me to send it back though. I will say this does not have the feel of a tough case. If it breaks too soon I will be back to update.
This was a great product that was worth every penny . I tried buying an iPad cover from apple and they wanted 40 bucks but I decided to c Wat Amazon had to offer and I'm glad I did . It took a little longer than I would have liked but about half as long as they said it would. Overall I'm happy :)
I bought this for just over $5 for an ipad 2. The front cover doesn't lay that great and it doesn't put the device to sleep. For $5 it's a decent item. Sure beats $40 for an Apple cover!
This cover is working very well. It fits my IPAD 2 and protects it. The only thing I dont like is the inside pad marks the screen and I have to clean the screen often.
This case is exactly what I was looking for. It looks professional and the slots on the cover display the iPad very well. I see a lot of complaints about the magnet, which is true it does not always lock the screen, but it does have an elastic band that wraps around the side to keep the cover closed, which does a great job of keeping the magnet in the right spot. For the price, you cant beat it.
I was used to just closing my other cover and it sealed very nicely - no strap, no hassle. Finally, the SANOXY cover doesn't turn the iPad off. You can see the bright lights from the screen pouring out through the grooves in the cover when it's closed. Well, I touched up the frays on my old cover and gave my mother that one. The SANOXY, at only six bucks, was not worth returning and headed straight to the landfill.
Love this case. I'm able to turn iPad two ways to view the screen. Snaps on and fits perfectly. It isn't as sturdy as I would have liked, but it does the job and for the price, I can't really complain. I purchased this case for MUCH less than my Dad who has the same exact case and paid over $50. Also, has a tight strap, which is hard to see in the pictures, but keeps the cover closed. Overall, good purchase.
Answer: No, nothing yet.  It has done an excellent job of protecting my wife's iPad.
