Verizon 4G MiFi doesn’t live up to the hype 0

I've been using my 4G Verizon MiFi 5410L mobile hotspot for about 8 weeks now, and because I was such a fan in the early days telling everyone to buy it, I think I need to give an update that tells the whole story, at least where I live and how I use it.   

To sum it up – when it works it's really good, and when it doesn't it's really bad.  It sometimes reaches and even exceeds their stated speeds.  But too often in their prime coverage area I get very poor or no service. 

What does Verizon say the speeds are? 5-12 MBPS

What do I get?  Here's this morning's commute on the New Jersey Transit train from Trenton NJ to NY NY as tested by http://www.speakeasy.net/speedtest/ to their New York Servers (first number is download speed, second is upload):

And according to Verizon's coverage map, this commute should be covered in virtually all "blazingly fast, brialliantly powerful" 4G.  But it's not.   

End of rant.
