The issue is that they never offer the actual listed speed. Not anywhere close to it. Mobile network is usually worthless in my experience these days in most busy cities. I might be waiting a good 2 minutes for a pageload if the tower is heavily saturated. That is most of my experience in fact. Websites like the mobile version of reddit are way too heavy and don't work at all. HN works, but the articles it links usually don't unless its an html blog post. Social media like instagram buffers terribly for crappy connections. Even the old guard youtube doesn't let you cache a large portion of the video anymore before playing.

I guess its a nice quality filter, but still. I can't be the only one but feel like the mobile web experience has taken a nose dive over the last 10 years as we got so many more mobile data users, and mobile web developers forgot how to write for slow internet speeds in the same time.
