Amazing device for people of all ages
Capacity: 4GB Ram 64GB Storage
I got this for my 11 year old as a device he could both do his homeschool lessons on and play on in between. Great storage capacity, it doesn't lag with decent wifi, great graphics and user ability is all around good! We even take it on the go and he uses it as a tablet on trips and the like! The touch screen makes this even better!

Great value.
Capacity: 4GB Ram 64GB Storage
I like this laptop. I think it is great value for my money. I decided to try a chromebook after Windows 10. So far this laptop works great!

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.
