Best tablet I’ve owned!
Style: Wi-Fi, Size: 128GB, Color: Blue, Configuration: Without AppleCare+
Fast, beautiful screen, and great battery life. The 11-inch size is the perfect middle ground for portability and productivity. Setup took less than 5 minutes. I am incredibly impressed with this iPad. The A16 chip makes everything feel snappy, from multitasking to heavy gaming. The Liquid Retina display is vibrant and crisp, making it perfect for streaming videos. Setup was a breeze, and the battery life easily gets me through a full day of use. Highly recommend for students or professionals! 5 stars!

Its Great! Except one tiny detail

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
