What our customer's say!

"On time, great price, works like a champ!", I really like my new cell phone. The option to add a 4GB memory chip adds to its usefulness. The downside was what AT&T wanted to charge for this chip -- over $50! Finding it here for less than $20 was a happy surprise. ChiTek delivered fast and it works great.

"Works as expected", Using it with a Sony Ericsson cellphone, it works just like it should. Can't believe that the phone originally shipped with a 256mb card.

"memory for SE W300i Phone", Put the micro memory chip to replace the 1GB I had in there. Recognized it as (close to) 4GB and worked with no noticeable slowdown.

"Good product.", I used for my Sony Ericsson P1 and work fine, some times onece every 2 moths maybe, give me a error, but suppose is the phone, just have to turn off and on, everithing is fine.

"Wow! Great Price, Lightning-Fast, no-error file transfers!", I bought this to use in my Sony Ericsson W580i Jungle Green Phone (AT&T), and I couldn't be happier. Wow. 4GB of storage, and I've used it for photos, video, and audio with great results.

My main reason for purchasing the extra memory was to be able to carry around the review/refresher/practice CDs (rendered into .mp4s) I obtained with Rosetta Stone V3: German, Level 1, 2 & 3, and this fits the bill perfectly.

Slap it into the card reader that comes with it and then into your computer, and read/write times are a flash. VERY happy with this product, and I saved more than half price -- compare Sony 4 GB Memory Stick Micro! Go SANDISK!!!!!!!!!!!!!

Five Stars PLUS!

Read this reviews before You buy...

"Decent Value, great product", This was a good price compared with other sources for the Memory Stick Micro. These memory sticks cost more than similar micro SD cards, however. Unfortunately Sony Ericsson phones only take the M2.

"Great price!", Great price for 4 GB of memory. If you go to a store or other places on the web, it's selling for a lot more. I bought this for my Sony W850i phone. Inserted into the memory slot and used the Sony phone software to transfer mp3 files immediately. I might even sell my ipod since I've been using my W850i for music - one less gadget to carry!

"Good purchase", It works as it should and was relatively cheap (Memory Stick has always been more expensive tha competing, and IMO superior, technologies but that's the only thing my brothers cell phone takes). The only gripe is the adapter converts to MS Pro Duo rather than regular MS so I can't insert it into my laptop's reader.

"I recommend it", SE Website stated you could use up to 2 GB Card for the SE K550i however, It is working very well with this 4 GB card... Fantastic!

"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.
