I had CLEAR back when they were called Clearwire. Many corporate name changes are designed to escape a poor reputation, and I have no doubt this is one of them. If you have CLEAR and you move to a part of town with poor reception, you drop packets. And, thanks to how TCP works, dropping packets == sabotaging your connection speed forever. And canceling my service with them was pure stress because they operate on a contract/termination fee structure.
Maybe they've improved since then, and maybe it's worthwhile if you just want a mobile solution and can pay for a home internet connection on top of it, but I remain skeptical.
Ya, it's no FIOS but With 4 bars on my modem's signal indicator Netflix usually works well. It's a little dodgy when it rains. Try moving your modem around your house and setting it at different angles. I initially had it in a position where it got three bars I moved it across the room and set it at a slightly different angle, now I get 4 bars and it's nearly twice as fast.
