I've had a Mobile Pixel Duex monitor for a long time and this Ofiyaa monitor. For me, Ofiyaa wins. Although I initially liked the Duex monitor, I really regret putting these magnets on my monitor as they damaged my laptop; Not to mention the included sticky pads keep falling off. The way this Ofiyaa levels up is MUCH better. Although it's bulkier in comparison, you don't have to attach ugly magnets to your laptop and it sticks and clings more tightly to your laptop screen. Another plus of Ofiyaa is that since the ports are on the other side of the screen, you don't have to see those ugly cables hanging from the secondary monitor itself. You can also use this on a table with a stand. Unlike the Deux, it also has an HDMI output. The only thing I don't like is the ugly "OFIYAA" logo at the bottom of the screen. The monitor initially feels thinner and more streamlined, but over time the magnet construction becomes a nightmare and the plastic sides are flimsy. You don't get deep blacks with this monitor (max brightness looks awful/washed out) and the colors aren't that impressive. However, an additional monitor really increases your productivity and is therefore definitely a must-have. I definitely prefer Mobile Pixels Deux.
