I have an SMC2642W. It works great! I\'ve never had a problem with it. The range is great too, but it does tend to drain the battery pretty quick if you have the lcd on along with it. I have used without a problem in OZ 3.2, 3.3.5, 3.3.6pre1, the tkcROM, and the sharp rom, and the cakco 3.10 rom. This is on my SL-5000D. I\'d recommend the card.
