I purchased from 24hourdispatch-Global and it arrived quickly.  The microphone was readily accepted by my iPod touch 3G and allows me to make Voice Memos.  I also tried it for a Skype call and it works!  Note other reviewers have noted you can't both have it in the iPod touch to use as a microphone and hear sound from the speakers - this is a limitation of the iPod touch, and I refuse to give this item a negative review based on the limitations of the iPod touch like so many others have.  You CAN use it to make a Skype call, and both speak into the microphone and hear through the speakers if you set the call to "speaker," either when making or receiving a call.  It's about the size of a very large pill.  I'm very pleased with the seller and the item.
