Its Great! Except one tiny detail
Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+, Style: Wi-Fi, Size: 512GB, Color: Pink, Configuration: Without AppleCare+
Ipad works great, easy to set up and everything transferred from the cloud from a backup I had (thank god because my other ipad is completely dead). Everything is in order except they put the magnets in the wrong spot xD. It doesnt matter functionality wise and I feel its more hassle to exchange than its worth so I am going to keep the iPad. With the case its in it doesnt really matter because theres a spot already for the pen.
4/5 stars

Great iPad
Style: Wi-Fi, Size: 128GB, Color: Blue, Configuration: Without AppleCare+
Great iPad, so much faster and stable than our old one (5th generation). Totally worth the price to upgrade.

Overall a Great Item!
Color: Y-starry Night, Color: Y-starry Night
This case is very nice and feels sturdy. The color is accurate to the photos, and the print layout looks great. It includes a side pocket that can hold some paperwork, and the material feels durable. The magnetic closure works well and closes securely. I’m not completely sure about the strap yet, but there is a designated spot for the pencil, which snaps in well and stays secure. Overall, the cover fits nicely and provides very good protection for the tablet.

Functional and great protection!
Color: Light Purple
Very nice case. Love the color. Case is exactly what I was looking for, it protects the iPad all around, corners and sides aren’t exposed. Pencil case is very convenient. Magnetic flip closure secures the case. It is a little heavier but that’s to be expected with it being PU leather and having a magnetic lock. I like the stand with different viewing angles as opposed to a case with a small trifold stand. Outside pocket is good for keeping papers you need to reference while working. Very compatible with my lifestyle. Great case for the money.

I love the design of this iPad case!
Color: 1-Black
This iPad case is one of the best purchases I have made in a long time! I love the design and the quality of this product. It has the feel of genuine leather and the stitching around the edges is very tight with no loose threads. A magnetic flap holds the iPad cover firmly closed when not in use, and at the same time can hold the cover open when the front cover is folded back behind the iPad case. An elastic strap on the inside front cover aids in holding the device with one hand when the front cover is folded back. It doesn't matter whether you are left-handed or right-handed; it will work either way. Just turn the iPad upside down if you want to hold it in your right hand with your hand through the elastic strap. The power button at the top of the iPad is easily accessible through a precisely positioned slot in the TPU back shell, as is access to the USB-C port at the bottom of the iPad. There are also holes in the top and bottom of the TPU back shell for the speakers. The two volume buttons on the right side of the TPU back shell interact well with the volume buttons on the iPad itself. There is also a place on the right side of the TPU back shell to securely hold a Pencil 1st Generation (Apple or non-Apple brand), and it is easy to remove when needed. A pocket in the cover is a perfect place to put a small microfiber cloth so that you can periodically clean the glass of your iPad. This iPad case is going to last a long time!
