i m currently using the 4gb MicroSDHC on my n95 for 3 months now and it works great! The reading/writing speed is even faster than the current SanDisk 2gb ultra 2, not to mention its capacity. i manage to put in 10 full movies with moderate quality on TVs(but really good on n95 screen). I got mine at ebay cost around RM250, but there are some fake ones on ebay too. The only way to test it is to fill the microSD to its full capacity and check if the files is still there and not corrupted.
