This was a great deal with the reader. It reads all of my cards.(M2 and MicroSD). You have to push the card all the way in and use the orange slide to push the card back out.

The card works great and the reader works great.
The card is fast and the reader is attractive and sturdy.
I've been using them for about 6 months. I have a couple in phones and several for storage, using the BlueProton reader as a flash drive -without any issues so far.

For the reviewer that didn't receive his M2 card I would suggest that instead of posting it as part of a *product* review and crying "WTF?", that he contact Blue Proton which is a great company and which I am sure will handle the problem for him. He asks, "What should I do?" Amazon conveniently provides that answer and more. Just read them.

Before these were bundled and there was just an offer of free shipping on one if you bought other I ordered the wrong product and even though it was my error Blue Proton still honored the offer after I emailed them and even after we both realized it was my mistake. So, I find it hard to believe they won't immediately ship an M2 card that wasn't included in an order. Did the reviewer even contact the seller as the Amazon guidelines instruct him to do before posting his review? WTF?

I sincerely believe that no one will go wrong with these products or with Blue Proton, especially at these prices. At least, I haven't.

The Sandisk M2 memory card works wonderfully with my Sony Ericsson z750a phone, and the Card Reader is great! Just put the M2 memory card into the reader, and plug it into any usb on your computer. On a mac, you'll see it appear on the desktop; click it, and then you can drag your files into it. I use it to store music from itunes onto my phone. It works like a charm, I highly recommend you to buy it and try it out! Plus, the shipping is really fast!

The reader is great and the best thing: it's M2 and SD Micro combo (you can use both cards). But mine came without this 2G M2 card! In fact there was no card at all. What should I do only with the reader??! WTF!

Quick delivery (I got an email Monday saying my item had just been shipped and I got it Friday). I didn't have any problems with the computer nor the cell phone. I really recommend this item. It's really really really affordable (it cost me almost $22, which is nothing compared to the $40+ it would have cost me at a store without the card reader). Honestly I recommend this to anyone who wants an M2 memory stick.
