Calibrated microphone for $15?!? (Parts Express/Dayton Audio iMM-6)

Dayton Audio iMM-6 Calibrated Measurement Microphone for Tablets iPhone iPad and Android
Seems worth the price if it does even just a bit...what I'm really wondering (particularly since the video doesn't play right now, maybe a browser issue) is if you can use this with REW or something to measure individual speaker drivers for design purposes. Or what else CAN you use it for?
(OR, would I need something more like this
Dayton Audio UMM-6 USB Measurement Microphone
which I admit I have not read the PDF because I suddenly feel to sleeeeeeeeeeppppppy...good night...)

Aside from calibration of the mike--- you need a calibration for your cellfone's external mike input. I suppose you could derive that yourself (it aint hard), but nobody ever does stuff like that.

You mean the deviation from flatness of at the input jack itself? Which I suppose you could measure by injecting small signal sine wave tones etc? Don't those offer "perfect sound forever"?!? (ha ha ha)

In the pdf it says you can get a "calibration file in text format
(compatible with most audio analysis apps)" from their website based on the serial number of the mic. (I know this is a bit off topic, is there a thread with views on audio analysis apps?)

I would really like to know if it's any good compared to EMM6 at least.

This one seems like it's to plug into a phone, so I'm wondering what applications are available. My perception is to really get into Room EQ Wizard you need one of the more expensive mics?

It can be used with a PC:

I did the obvious exercise and made up a few serial numbers and they are different (a bit of variance unit to unit) with the absolute sensitivity at the top of the file. Hard to believe at $15. You might have to use a spread sheet to put it into a format for your own software.
