Actually honest review
Style: Convertible | Touch, Style: Convertible | Touch
I personally wanted it just for the work. I wasn't in the need of a laptop, that's why I bought a chromebook. 1. Packing is awesome (ASUS as always good), nice box with handle, inside of it the chromebook itself and 45W USB-C charger + some papers. 2. Setting up was fast, since I have an Android, but with the iPhone works the same, just scan the QR code and it'll download all it needs. 5 minutes and you're ready. 3. It's 2-in-1 with touchscreen, so you can just flip the screen and voila, now you have a tablet. Touchscreen is good 4. [UPDATED] Average battery life 7-8 hrs while working \\\ Battery life, one of the main things I bought it. It's really up to 11 hrs though it says it varies. But if you're gonna use it just for work as me, it's going up to 14 hrs. (you can see on my photo) 5. You can download Steam and theoretically even play some games on it, but I don't think it can run much 6. Weight, if it's really matter to you. It's 3.6 lbs, but I don't really care about it 7. It's pretty fast, sometimes might be a little bit slow, but it's already an hour I'm using it right now and there's no glitches or anything else at all. I think you just need to give it some time to "heat up" 8. Full functionality of a chromebook, I don't even know what to tell you here 9. Price is kinda high, me personally bought it because of the touchscreen, but if you really need just a tool for work, buy either a simple version of this chromebook or Google Pixel Go which is much cheaper. But if you want a good 2-in-1, buy it. I don't have any cracks on it, the delivery was good and fast and the chromebook book itself made awesome. I already have a gaming laptop from ASUS and these guys know how to do it! It's a nice device for it's price. I'm gonna use it for a while and then make the updates.

Great Chromebook at a Good Price
Style: Convertible
My job has required that we use Chromebooks for about 7 years now. I was a MacBook user for years. Recently my MacBook died, after probably 7 -8 years. I love Apple products, but I couldn’t see spending so much money on a new MacBook for my personal use. I bought this Chromebook and don’t miss my MacBook at all. Using Chromebooks and the Google Suite for work helped my transition. There are definitely things that I miss, like iMovie, but I’m sure there is an app out there if I need something similar. This Chromebook is well-built, a great size, has a good display, and it’s fast. I highly recommend it.

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.
