I have the 328P6VUBREB. Not very impressed with its performance. It takes forever to wake up and randomly drops connection with my computer via Usb-c. On paper it ticks all the boxes. In reality, it is a love /hate relationship. Much happier with my LG. Neither are perfect with Usb hub performance but LG is better.
