So far my test with model B2 have been promising. It worked right away:

I don't hear static and the recorded voice is loud. I have a very faint echo in the room and the microphone picks it up. I plan to use this for speech to text and voice recognition so I'm hoping the audio is clear enough with the echo to be usable.
One last point is this uses very little power. I'm using a 2A supply for my Pi and its able to power devices in all 4 USB ports, including this microphone, as well as GPIO components.
Overall, 4 stars until I have a chance to test voice clarity and accuracy for speech to text.
For people looking to do some technical Raspberry Pi stuff, this microphone does not work with RPI v1 but it does work with RPI v3 out-of-box. When you connect it to the USB port it is automatically detected and you can see it in the "arecord -l" output. Under the Linux OS it appears the sound recorded is a little bit low. You may need to normalize (increase gain) on the sound using a program like mp3gain, ffmpeg, sox, etc. or better yet increase the gain on the sink using pulseaudio. If you raise the volume to high you will get a lot of static, which is to be expected.
Bottom line, the mic is solid considering the price point! You can't complain about the functionality given the price point. I can record myself from the other side of the room. If you are looking for amazing mic quality then buy a bigger more professional mic.
When listening to play back it's clear there is a lot of static unless I'm talking directly to the mic. It was able to function for voice recognition using the Alexa raspberry Pi build. I installed the wake word "always on" so that I didn't have to press a button to activate, and then it works but again only if you are close to it so it's not going to work if you want to build your own that sits in a living room.
Given the size and price this is one of the easiest ways to add a mic for <$10, but if you are expecting high quality audio maybe keep looking.
I purchased it primarily to use Cortana on an older PC that doesn't have an internal microphone, but so far it hasn't worked on any Windows 7 or Windows 10 PC I've tried.
Also worth noting: the packaging actually has a blister card for a different product (a full size microphone with power indicator, stand, pivot, and 8-foot USB cable). Also, the seller accidentally sent me two of them, even though I only paid for one, so I don't think I got a dud--they both perform the same.

I've built Amazon's Echo/ Alexa on the Pi and this microphone works perfectly. I don't have to shout and can be 7 feet away.
No drivers were needed.
There were some configurations i had to play with on the Pi, but those were specifically for Alexa, otherwise this mic worked straight out of the box.
I'd definitely buy again.
It's also a *very* tight fit in a USB socket and is already showing signs of splitting - after barely 10 minutes of testing.
Returned for a refund.
Once I set audio levels correctly on the Pi it works really well.
I can speak to the Alexa/Pi from anywhere in the room and Alexa understands my Scottish accent almost all the time.
The microphone is plug and play, picks up sound easily, very unobtrusive.
Skype recognises it and accepts as default but it does not work. (May be a software problem with skype - anyone know???)
Unqualified praise, buy with total confidence.
