Pros: Have had very good results with these for some time. Best price/performance I have found so far. Seem quite fast, and no reliability issues so far. Packaging seems plenty solid too Have been my favorites
Cons: non so far Don't know about long term retention,
Pros: I needed a MMC card that worked well which my raspberry Pi as well as my Amiga via the IDE<->MMC adapter which meant a lot of reads and writes and after having these for approximately 5 months now it has performed perfectly. I will probably be buying more for my vintage system conversion and backup.
Summary: This SD card is perfect for what I need. Used this on Vacation and it worked amazingly well. When I went to transfer it to my computer it went blazing fast. The SD card itself is Waterproof, shockproof, and X-Ray Proof. If anything goes wrong with the SD Card, you will be covered by a Life Time Warranty. This SD card is just like a normal SD Card but the speed on this card is much faster than the ones that I previously owned.
Summary: These cards are excellent, we have 3 now and use in camera and laptops with no complaints, video we find is excellent also quality. Also use their portable drives. Would recommend this brand to all.
Excerpt: купил 2 одинаковых карты.Одна пока работает, вторая умерла после первой записи.через месяц не смог ни стереть, ни отформатировать.Обратился по гарантии.Сказали высылай в Китай за свой счет-вышлем новую.На фига такая гарантия нужна. вобщем шлак.
