Touch screen, long battery life, and it has a MicroSD slot on the side. Missing a backlit keyboard
Style: Convertible | Touch
Overall, this is a great computer for the price. It's not the fastest, but it's not the slowest. I just wish it had a backlit keyboard. And computers or laptops that have backlit keyboards are usually on the pricier side. They should make a Chrome laptop that has a backlit keyboard that is under $300. Anyhow, it starts up real quick, I noticed that it is a little bit heavy, but that's a good thing because if the battery is lasting a long time and it does seem to last a long time, then I'm okay with it being heavy. I've always trusted this brand, and I also like that it has a touch screen feature. With that being said, if it has a touch screen feature, it should automatically include a backlit keyboard. Anyhow, great computer at a great price. The big selling point for me is that it had a memory card slot for your memory cards. I have a DJI drone, and I needed a computer or should I say a laptop that had a memory card slot on the side and this one has it. And you don't need the big adapter that comes with many micro SD cards. The micro SD card fit perfectly into the slot on the side of the computer

Look elsewhere for a different device. This is garbage
Style: Convertible, Style: Convertible
I normally don't write reviews, but when I do it's either for something outstanding or something that should be steered clear by everyone in the general public. Unfortunately, this one is for the latter. I purchased this device to begin with as a laptop to be used by my son for Chicago public schools and allow him to be able to access his school work. Upon receiving the first unit physically, the device looks and feels wonderful and within 2 days of starting to use it. The screen was no longer capable for touch capabilities and the keyboard was non-functional as well. I called their customer support line at Asus and Asus. Couldn't figure out what was wrong either, but I was supposed to pay to send a device I just bought to go have it repaired by Asus and this is why I say their customer service is knowledge below standard but I would say some of the worst there is on the market today. Amazon luckily was able to step in and send me a new unit as a replacement. Amazon's customer service is some of the best I've ever you dealt with. Got the new unit and now this one over here. Can't even stay connected to Wi-Fi. My kid can't do his homework. This computer is a total piece of garbage even for something as simple as a means to do homework for a grade school. I will never touch another asus device again and I would advise anyone else that is looking into this product to look elsewhere to avoid the frustration that I'm going through right now

Best product in this price range
Style: Convertible | Touch
Purchased for my seven-year-old daughter. Since she is young, I didn’t want to spend a lot of money on it. This is a sleek and durable Chromebook with a long-lasting battery and large screen, perfect for watching movies (which she loves to do!). So far I haveno complaints or reservations about it.

The Ninja slushy maker honestly surprised me. It’s quick, easy to use, and makes frozen drinks with a smooth texture that actually feels restaurant-quality.
