Summary: Wow this thing is so tiny, when handling the card, it felt like I was going to crush it. I stuck this into my new razr phone and it works great. Seems to be compatibile with it. Turned my phone into a mp3 player now. Package also includes an SD adapter which is useful for my card reader. Highly recommended!

Summary: Works well in my HTC Tytn phone (aka Cingular 8525). The adapter lets me plug it into my PC memory reader too, for faster transfer of files.

Very tiny - I keep thinking I am going to break it or lose it (not a Kingston problem, just a comment about MicroSD in general).

Summary: Purchased this MicroSD from outpost.com for $29.99 and have been using it in my Sprint Fusic phone for over a week. Used the supplied SD adapter to transfer mp3 files from my PC using an SD card reader. Write speeds are very good.

Inserted the card into the phone. It was recognized immediately and was able to play the mp3 files just fine. Used the camera in the phone to take multiple pictures and videos. Writing to the card from the phone also works well.

Also used the card with the SD adapter in my HP Ipaq and was able to successfully read and write data.

The only issue I've had with the card is its snug fit in the supplied adapter. It was a pain to coax the card back out of the adapter without exerting undue force. I've used other microSD cards in other SD adapters and those have all been a lot less snug.

All said, it is definitely great value for money and I would recommend it.
