Just Love this.... Read On!
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi + Cellular
Like knew and seems to have been powered on one time only. Apple treat it as a new device. Its spotless and works great. I have had several ipad pro's and decided to by this instead and I actually prefer it. It does everything I could do with my ipad pro 2020 and then some. Its faster, good cameras. The e-sim card works great though I do wish it had a physical sim card slow.. oh well! The battery life is really excellent, it was quick to set up via a transfer from my old device. I added a case that looks like a fancy note book and love it. This helps with drops and scratches. I have not added a screen protector yet. The storage capacity is the same as my old ipad pro, I will never use 128 gb anyways... To sum up, this gets 10 out of 10... and its a great replacement for a ipad pro!

Good quality, good price, bad shipping tho
Color: Silver, Memory Storage Capacity: 128 GB, Set name: Wi-Fi
Honestly I was really happy with the iPad. The one I got was RENEWED in Excellent quality. I will start off by saying that it was poorly packaged during shipping and the iPad box was severely damaged, but luckily my iPad was just fine. The iPad came decently, but not fully, charged and was quick and easy to set up. The battery life does not last as long as my Galaxy Note 20 Ultra, but I am also sure I do not have it optimized for battery saving. I got this iPad for 2 reasons. 1) To be a pseduo laptop with a keyboard case for school, and 2) procreate. I am overall happy with the item. I'm just sad I found a better deal on the exact same model sold at Walmart and its in pink (;-;). The item functions well, and is as described, it was a really good deal
