A knock out of the park!
Got this for my partner who travels a lot and needs at least two separate screens going to do his job more easily. He normally has 3 screens up at home so for his birthday, he got this triple monitor. He does need to hike up the resolution to 120 to see the screen clearly but is quite happy with having 3 screens when he needs them. The item was heavier than I imagined but he's happy with the product.

MNN does it again!
This is such a great tool! I typically use three total screens (laptop + 2 stationary monitors). When I travel, I have the MNN single portable monitor. The single monitor worked for my short-term needs but I'm in the middle of moving (and had to pack my stationary dual monitor setup) so I needed something to help my productivity for a longer term. This is perfect for what I need. The only "downsides" to me are: - One monitor folds backwards, leaving the screen exposed. This is not that concerning since it comes with a soft case, but it would be a super neat update in the future. - the weight of it will cause my laptop to close if it's not balanced correctly. The monitors come with a kickstand in the back to prevent it from falling backwards, but it would be really cool if there could be a front kickstand in the future. All in all, I'm thoroughly impressed that MNN was able to offer this cool product at this price. Can't wait to see what MNN does next.

BUYER BEWARE
Would leave less than 1 star if possible -- this extender is so heavy that it actually broke my laptop screen, that I then had to take to Apple and have paid to fix. Overall, this extender does not provide enough 'support' for the additional screens, causing the majority of the weight to be born by the laptop monitor, and causing a crack in the lid angle sensor and screen. Tried reaching out to the seller, they stopped responding after I told them the issue. They are unwilling to allow me to return it or provide a refund.

I love this! Folds down flat for transport.
I love this thing. If you are used to having multiple screens at your computer, this thing is perfect for on the go, or just working at your kitchen table without pulling all of your monitors out. The best part about it is it has one cord that connects to a port on the laptop and to the monitors. You do not need an additional power cord from the monitors to the wall. Also, the bezel is thinner than all the others, and the color is vivid on the monitors. I recommended it to many people and everyone always asks where I got it.

Screen problem!
This is the inner screen that is protected at all times. Nothing fell on it and it’s always protected. Screen seems to be very cheap and not durable.

Firewall issues
This item was returned and I did not use it. The newer Lenovo laptop I brought it for didn't work. The download to connect and activate the screens was blocked by my employers fire wall. Make sure you can download the correct software. Very nice, built well, designed.

Too bulky
Too bulky …. Kick stand cheap and does not work well ….

Privacy warning - product requires screen recording
It's unclear why this laptop extender requires screen recording as a part of providing its service. It's also unclear whether the data will be shared externally, so I will be returning it.
