heat distribution is great so far on smaller items. the larger roasts, etc need some turning and lower levels to be thorough on the outer areas. cleanup is great, just some warm water and soap and a soft sponge. i'm not a ceramic pro but it's been easy so far.
i got this card specifically to expand the memory on the samsung focus. it has performed well so far (2 weeks), using over 10gb so far. zune transfers remain fast, music playback is smooth, apps do not lag. the user interface of the os will freeze occasionally, and apps sometimes require a couple tries to start, but i saw that before the expansion as well. the device has gone through three deliberate restarts, no problems with memory count after each.
got them to listen to music at work without bothering others. they may not be "studio", or "reference", but they're pretty solid in that context. i listen to a lot of alternative rock bands and orchestral soundtracks, i hear very little distortion in those ranges, at fairly high volume. ear padding is quite comfortable, just builds some warmth after a while; i can wear them for about three hours before needing a break. great value for the money in my book.
