Review on 4K Portable Dock - USB C to HDMI Adapter with PD Charger, QCEs USB-C Multiport Hub for Samsung Dex Station, Galaxy S20, S10+, S9, S8 Plus, Note 10/9, Tab S4, MacBook Pro/Air 2019, iPad Pro by Christian Young

When I bought this I knew I might have problems with it. Other reviews say you either get the good or the bad. Mine works, but if you plug it into HDMI, the mouse, if wireless, will work just a few feet away. Also, my phone doesn't charge when using HDMI, just charges. When I disable HDMI, the mouse works fine on my phone screen and charges quickly. But a genuine Samsung product costs around $90.
