Really wish there was a 3.5 option because this product is not quite a 4 star but is better than average.
Pros
,The materials used seem sturdy enough
,Came package appropriately (the exterior of my box was damaged but not the contents)
,Only needs the included power supply. (package includes a short usb type A to micro cable for drawing power from the monitor's controller board)
,Includes a small fan.
,Price
Cons
,No instructions
,Sticker on the mirror said to go to mm.vilros.com, yet site doesn't exist
,Only includes a mini HDMI to HMDI cable (seems to want you to use a pi zero W yet product description makes no mention of this)
,The hot glue holding the inverter in mine failed during shipping (inverter is loose in the back of the mirror)
,No dedicated mounting for a raspberry pi
Overall, I'm happy with it. I used Magic Mirror2(https://magicmirror.builders) on raspberry pi 3B and my own HDMI cable. If Vilros addresses cons, this becomes a 4 to 5 star product.
