Perfect charger
Size: 10FT, Color: White
Very impressed with how quickly the charger works. The longer cable has made it easier to use the phone while charging and sitting on the couch. No issues with the cable getting tangled or fraying like I have had with others, or pinching and breaking the connection.

Life changing little screen
Size: 15.6" 1080P, Size: 15.6" 1080P
I was losing my mind trying to work from home off a single laptop screen. Secondary displays were not connecting to my computer outside of the office, IT could not figure out the issue so I was doomed to single screen anytime I worked from home. A co-worker suggested I take a look at this style of screen. I had my doubts that it would work with my lap top, and lo and behold I am back in action with a dual display. It comes with an HDMI cord option and a USB-C cord option (you do not need to buy separate cords, they are included). I used the USB-C as it also acts as a power cord to power the display. It took two seconds to hook up, and with one setting change on my lap top the display successfully extended (does not just duplicate your display, it will allow display extension as well). The image quality is more than sufficient for work (no opinion on PC gaming) and settings such as brightness were easy to adjust. It's the perfect size for use with my lap top screen, and they had plenty of additional size options. The built in stand allows two screen angles, and acts as a cover when not in use. For the price this thing is absolutely clutch, don't waste money on expensive displays - you can use this with any USB-C capable device so it can travel with you for work or fun. I will be interested to see if it has longevity, but for now I'd give this thing 10 stars if I could.

Great product for a great price
Size: 15.6" 1080P
I REALLY like this. I need 2 screens to do my job efficiently and have struggled lately when traveling. Splurged on this for myself and was really impressed. It’s nice and lightweight but feels sturdy. The image quality is good. The set up could not be easier. This is a game changer for me.

Works pretty well for a cheap monitor
Size: 15.6" 1080P
I work remote and travel, so I miss my multi monitor setup. Not anymore. I took this on a trip with me and it was great. The stand folded over to not take up too much desk space, the cables wear just long enough, another 6” would have been great but they worked. Quality of the screen is plenty good enough for office work, I have no gaming or artwork experience with it though. If you need an inexpensive 2nd monitor , this works great for on the go or even for a regular desk.

Great portable second screen
Size: 15.6" 1080P
Really convenient for a second screen on the go. The display looks sharp and it’s lightweight enough to carry around easily. Setup is simple, just plug and play. Not super bright, but works well for most uses.
