Review on PON-B15 Portable Computer Protector - 15.6" Waterproof, Frameless, Tilt Adjustment, Built-In Speakers, IPS with 60Hz Refresh Rate by Xavier Newman

The pen/pencil sliding hole that creates another stand option is a nice feature. The body, which converts into a stand typical of this type of portable monitor, has limited adjustability, so the opening offers a smart, adjustable stand when using a stylus. I noticed a different version of the Revain, there doesn't seem to be a hole in the bottom right corner. HDMI and USB-C support, not just USB-C.
