Review on ABC Products USB Multi Digital Camera & Mobile Phone Memory Card Reader Writer - All-in-One Plug n Play Photo Transfer & Digital Frame, Supports All Cards (Smart Media Excluded) - Includes Cable by Carlos Abood

I'm writing this based on my research and before I get mine on May 4th. I say OK and will update next week. I've used other memory cards in devices and then upgraded to larger cards, so I bought these to keep using them. This is a read/write device. There were questions. Before asking a question, read the entire entry in; "Product Details", "Product Description" or "Search Customer Reviews" at the bottom of "Latest Customer Reviews" in the middle of the page. 1. Reads all cards except Smart Media. I took the types from the graphics card it comes in. XD-H, XD-M, MS DUO, MS PRO DUO, MS PRO, MS ROM, MS PRO MAGIC GATE, MS DUO MAGIC GATE, RS MMC 4.02. Works on Windows operating systems up to and including Windows 8. Questions about working with the manufacturer, if Windows works, it will work.3. If you need more information, please go to http://www.abcproducts.com/index.php?route=faq/faq&fpath=7#faq_24. This is a very good video. Pay attention to the MICRO card, it is upside down.4. I looked at other readers and this one has the highest number of cards listed for reading. (I'm not affiliated with ABC, just someone who researches what I buy before I buy it).5. Questions about music, photos, etc. Answer: If you can put it on your computer's hard drive, then you can put it on any memory card. I look forward to using this with the four cards I have. It becomes easier to take personal information with you when you leave home. UPDATE May 05, 2015: I've upped the stars to four because it actually reads and writes the MicroSD and SD cards I put in it. 128GB MicroSD. I was looking forward to using Reader/Writer, but now I'm very disappointed. It's a bit confusing at first glance. The MicroSD card is really inserted upside down, contacts facing up. What's up now? The company name is written in RED letters and is at the top, making it top.2. The SD card is inserted with the contacts facing down. Inserting a MicroSD card can be a little frustrating since it's so small, about the size of a dime. The MSD slot is located under the SD card slot.3. The big disappointment is that I put in SD and MicroSD cards and the only card that showed up in Windows Explorer was the first card I put in which was an SD card. I decided to check this fact and first inserted MSD and then SD and the result was the same. I wanted to slot the other cards I have into the reader at the same time and take advantage of the extra 32GB I have. Sliding cards in and out can wear down the contacts and eventually render the card unusable. If anyone knows how or why this map is not being read at the same time please let me know. I'll keep this for a while and try other cards I need to see if I'm right. Maybe ABC Products will say something.
