Great monitor
Size: 27 inch 100Hz
I love this monitor! It has very easily adjustable setting, with brightness, blue light filter, and resolution. It’s a very nice monitor and it was easy to assemble on its awesome, adjustable, and easy to set up mount. I have moved it around quite a bit and it has not broken. Very durable.

Best fan ever
Color: Brushed Aluminum, Style: 3000K Warm White LED
Fan works great, light is more than bright enough to light a large room, fan is great, on high it will provide more air than you will ever need, also works with Alexa flawlessly so that you dont even need the remote or your phone.
