I thought I was purchasing an electronic portable display called a BladeX from saintine.store (aka RunPeng Network CO.,LTD.) and received a magnifying screen.

Here’s a PDF of the page in case saintine.store decides to pull the product page

The electronic digital display is described as:
BladeX, The Slimmest On-the-Go Monitor
BladeX is one of the most lightweight and compact on-the-go external monitors available today. At under 2 pounds, it is easy to store and travel with. It’s available in 1080P and 4K high definition versions and this 15.6” monitor promises to boost your productivity by up to 50%. The BladeX is notable for its super slim 4.5mm profile and makes the perfect travel companion. Just plug into it with USB-C or HDMI and you’re ready to work with the convenience of double monitors wherever you are!

What I received was a “Mobile Phone 3D Video Amplifier” Enlarged Screen Magnifier.

Here are pictures of what I received

Saintine.store is obviously a scam
