ASUS Chromebook Flip CX1 touchscreen - extraordinary value
Style: Convertible | Touch
The ASUS Chromebook Flip CX1 is excellent for what it is designed for: light computer work, some work as a tablet, easy to carry everywhere and well built. This is not a gaming computer or for anyone doing lots of graphics work, but it is superb for basic word processing, zoom meetings, note taking and as an extension of your phone. The connection with the phone is seemless and can be used as an extension of the phone including running phone apps, sending texts and tethering to the phone. It is an extraordinary value for what you are getting which includes a convertible laptop and touch screen.

Great Chromebook for Everyday Use
Style: Convertible
I’m very happy with this ASUS Chromebook. It’s fast, lightweight, and extremely easy to use. ChromeOS runs smoothly, starts up in seconds, and handles everyday tasks like browsing, streaming, emails, and documents without any issues.
The battery life is excellent, lasting most of the day, and the design is slim and comfortable to carry around. The keyboard is responsive, and the screen quality is good for work, school, or entertainment.
Overall, this Chromebook offers great performance for the price and is perfect for students, home use, or anyone who needs a reliable and simple laptop. Highly recommended.

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
