Its nice to have, but they charged you way more than they should have, at that price, no its not worth it.

From my testing specifically from fast.com, every now and then when I run the test run and it glitches a bit, I will see the stated speed slow down and then spikes up, my theory is its using a rolling average, while the spike didnt register some data downloaded it later registers is and gives you a higher than normal average.
