Customer Reviews

Lots of Room in a Small Package
I bought this 4.0GB M2 memory stick to use in my new Sony Ericsson w580i Walkman phone. I've loaded about 850 songs so far and it works great. I've still got about 1.5GB of room left. What a great product at a really reasonable price. BTW - Sony Ericsson's website says the phone can handle up to a 2.0GB M2 card. They are incorrect. If you want more music on your phone, go with the bigger capacity card.

makes your Sony-Ericsson phone much more usable
When I received the M2, I put it into my W580i phone (I turned the phone off, inserted the card, and then turned it back on), and the memory stick was detected right away, no formatting needed. I transferred pictures from phone memory to the memory stick, and then connected the phone to my PC to download MP3s and podcasts. I was even able to download an audiobook that had been saved as an MP3. Using the Sony-Ericsson software to do the downloads and file transfers was very easy. I have been using the memory stick for a couple of weeks, and there was one glitch. Once, when I was using the phone, the card was suddenly not detected. I shut off the phone, removed and re-inserted the card, and turned the phone back on. The card was detected again. My only other "gripe" is that this is yet another memory card format for us beleaguered consumers. Having to get this memory card was my biggest concern when I upgraded my family cell phones a few months ago. We had already been using phones that accepted microSD cards, and microSD cards are extremely affordable nowadays. In comparison, M2 memory cards are rarely available at most stores, including electronics retailers such as Circuit City (which sells Verizon Wireless which doesn't use Sony-Ericsson phones). And retailers that do carry M2 cards (such as Radio Shack or Wal-Mart) have it priced much higher than microSD cards of the same capacity. Also, the M2 card is so far used only in S-E phones and nowhere else. Without the Pro Duo adapter, it would be a very limited-use card indeed. Now I may even attempt to shoot some video with this phone and card.

works like it should
I use it with my Sony Ericsson W580i. The thing about these cards is there is very less chance for them to go wrong, and that makes it more compelling to buy it from online store like Amazon (if costing less than half of what it would in a store near you is not compelling enough). I got mine here at Amazon, but I think the order was serviced by Blue Proton. The card shipped quickly, and it works like a charm on my 580i. Lots of room for music and photos. After 4 months, it is yet to create any problem.

Contrary to what another reviewer mentioned here (which is why I am leaving this review), this does not come with a card *reader* (i.e. there is no USB card reader to use with your computer). It comes with an adapter to convert it to Memory Stick Pro type (a bigger variant of memory stick cards, typically used in cameras and camcorders), but thats all it has. If you plan to use it with your computer, you need a memory stick pro/memory stick micro (M2) card reader on your computer (USB reader or otherwise).
