Had to verify it was not new, perfect condition
Capacity: 4GB Ram 64GB Storage, Capacity: 4GB Ram 64GB Storage
This arrived totally beautiful, does not look as it had ever been used, I had to look at my order to verify it was reconditioned, very fast, battery life is decent, everything works as it should, it came with stylus.
I love this laptop other than I wish I would have done more research into Chromebooks, not a fan, old school always used windows , this is a shock to my system, even though I have android tablets and phones, I should be comfortable with this but I am not, it said buisnesses and education, I can see where it would be great for education, not as much for business (just my opinion) . It does not offer many things that through the years you become a custom to with a laptop. Time will tell if it can offer what I expected to use it for.

Great computer for fair price
Capacity: 4GB Ram 64GB Storage
This is such a great idea - half iPad, half computer. Love it and it's not very expensive. I'm pretty much an Apple person and this has changed my mind some.

It died in a month
Capacity: 4GB Ram 64GB Storage
Bought it for my middle school daughters online classes. It stopped working in a month and few days. So disappointed and upset. If you are going to sell something, sell something that will last for at lease a year not a month.

Love love love!!
Color: Ultimate Sticker Making
10 out of 10 product. Its super easy to set up and use. The quality is top notch. It works faster and better than the older maker models and I love the bundle. Its perfect for beginners, gives you a bit of everything to try. Great for the amount of money. If you can get this, I highly recommend. Im actually obsessed
