User Reviews about Sony MSA2GU2 2GB M2 Memory Stick Micro (Black)

This card works great with my Sony Ericsson S500i phone. Of course, it probably works great with any Sony phone - but now that you've read it, you know it must be so. -- Sony Ericsson S500i Compatible

Tiny, tiny and they work! I purchased two for replacement of those robbed by AT&T from the Sony Ericsson W760a cell phones. Seems they remove or make the manufacturer strip the phones of certain items normally included so they can sell them. Surprise surprise! These are made by Sony and original equipment for their phones. They are as advertised.
-- What's to Say

I bought this product to put into my Sony Ericsson phone. It works exactly as I expected, and allows me to store photos on it, as well as MP3's, which I can then use as ringtones. Great buy. The reader is very easy to use--no problems at all. -- Works as advertised...

I bought this for my friend for her birthday. It was half the price that they wanted for it at Best Buy. She uses it for her new cell phone and says that it works great. Amazon offers a lot of great deals and prices. -- works great

Bought another one somewhere else and it never worked. Bought the Sony MSA2GU2 2gb memory stick through Amazon. Got a great price, and Amazon delivered right on time. My son popped it in his phone and he was good to go.
I totally recommend it.
