Works great
Color: Purple
Works just pretty good. My only complaint would be that it can turn on the screen when closed. I put it in my backpack and went throughout my school day only to find out later the battery had drained because the screen would light up and stay on.
Did not have this issue with other covers. Easy work around is to just do a complete shutoff or maybe change the settings before putting in away. I just had the habit of keeping mine on because of frequent use in back to back classes.

Great case & keyboard combo
Color: Navy Blue
Great case! Updated my son’s children’s case to this one and he loves it! He feels like it’s a laptop now. The magnetic feature is great & it’s super easy to install!

Cover is nice, keyboard could be better
Color: Navy Blue
The cover itself is nice. The magnetic closure works well. It fits my iPad really well. It’s a good case for the money, but the keyboard feels pretty cheap and flimsy.

Great low cost USB C to 4K HDMI splitter adaptor
Color: Black
The Anker USB C Hub 5-in-1 USBC to HDMI splitter with 4K display with one powered USB c and 2 USB A ports works flawlessly and is a perfect travel companion or simple and inexpensive desktop dock to connect a moderan USB C only laptop to a large monitor up to 4K resolution. It supports 4K at 60 Hz so not for high speed gaming but it is flicker free for daily work where running at 60 Hz provides a clean looking 4K display. The USB C and USB A ports work perfectly. I already have four of these in different port configuration but wanted the 4K extension for travel and this was the best one for quality and bang for the buck.

Compact, Travel friendly, Works well with ROG ALLY
Color: White
This is a compact and well built adapter, and it is travel friendly. I use it for my ROG ALLY when I don’t want it docked and still need charging and other device inputs. It has just about enough ports for what I need, usb-c power delivery port for charging (ROG ALLY can still run at maximum performance using this with a 100W charging brick and a cable that allows 100W power pass through). I use the remaining USB-C port and two USB-A ports for external hard drives or gaming controller 2.4Ghz receiver. Transferring files between ROG ALLY and an external SSD with this adapter is fast, could reach above 380 mb/s. All the device inputs were as advertised, “plug and play”. The hdmi port also gives me an option to connect my ROG ALLY to TV when I don’t have the dock which takes up more space for traveling. One thing to note, you will have to use the USB-C port on your PC which provides more power (usually at the back and not on the front of the pc), if not plugged in to a power source. When I received my first order, I plugged it into the front USB-C port of my mini PC, just for my wired keyboard and mouse, the computer didn’t recognize it and couldn’t get any input from my keyboard and mouse. I returned the first one and thought it wouldn’t work as I expected. A few days later when I was using another Anker 7 in 1 USB-C adapter, I ran into the same issue but I know that adapter had been working well, then I realized I had to plug it into the port on the back of the PC. So I got this again and tried, it just worked like a charm. Hope they actually mentioned it on their product page so I wouldn’t have to return the first one. The cable length on this adapter is just right, not too long or too short when using with ROG ALLY (not hanging, since the cable is pretty sturdy, when I picked up the ROG ALLY, the adapter just comes along).
