Five USB Bitcoin Miners in Comparison- Bitcoin Mining

Hey guys, I'm new around here. I have seen multiple "coin miners" on sites and a couple advertising for 2GH/s Speeds. Like this one here: http://www.amazon.com/BPMC-Fury-2-2-2-7-Bitcoin-Minedp/B00GRJUE0Y/ref=sr_1_2?s=pc&ie=UTF8&qid=1399944259&sr=1-2&keywords=coin+miner
Not sure if good deal or no? Or what the actual usage would be for DogeCoin mining as in the mining pool im in only utilizes a max of 700MH/s... Any help is greatly appreciated!!

Are thumbdrive miners any good?

I have seen posts for thumbdrive miners such as these:
BPMC Red Fury USB 2.2-2.7 GH/s Bitcoin Miner
Dualminer Litecoin Bitcoin USB Asic Miner
and these are used either with standard USB ports on your PC or on a multi port base such as this:
Etekcity® Premium Upgraded 10-Port External USB 2.0 Hub
This seems like a relatively cheap, scalable and low power solution for mining but I am not seeing it mentioned in the posts in this subreddit. I am a newbie and would welcome any information or advice on these units.
Edit - I removed links since purchase links are not allowed.
