I've no experience with those, but at those prices, it may be overkill if you just want to use your phone on a monitor and/or with mouse/keyboard. I've used it with one of those sub-15-dollar hubs (most are flat, small, rectangular 4-port plus HDMI hubs) with one of the myriad of chargers I have lying around the house with no issues. DeX is nice, but not all that powerful and will not be able to take full advantage of the extra features on those overpriced hubs, TBH. I'd only get those if you have something else you'd like to use with them (like a more feature-packed laptop/computer), but to each their own.
