I have been experiencing very slow 4G speed for past few months at my work place (southeast Boise). The speedtest gives a download speed of ~0.2Mbps for 4G LTE, and I couldn't even stream online radio smoothly!
Have been a Verizon customer for past 9 years, and seriously thinking of switching to T-Mobile for faster 4G speed. I know I will miss the great reception Verizon provides when I am on a road trip, but getting only 0.2Mbps 4G speed in places most of your time spent on is not acceptable.
