Kingston 4 GB microSDHC Class 4 Flash Memory Card SDC4/4GB

Not sure what these are listed for right now, but prices were pretty stable around 12 bucks for awhile, when I got mine to go along with a new device that was capable of taking advantage of High Capacity Micro SD cards. I wasn't looking to spend a whole lot (actually around 12-14 dollars), and was hoping to find an 8GB one. Unfortunately, they were around 20 (still a good deal if you NEED 8GB), so I went with the 4GB. My regret is not regarding the size I got, actually, it is that I didn't learn more about what "class" meant in regards to to the cards. I now know it refers to speed, more specifically transfer speed. Essentially, for the people out there not too into the technical aspects, the higher the class number (4, 6, 8, etc) the faster the transfer speed of the card. For my current purposes, it's not a big deal, and noticeably faster than the regular MicroSD cards (I had a similar device before that was almost identical, but couldn't read the HC cards, and got a new one that could, which was just about the ONLY difference between the devices). However, anyone purchasing this for a higher end digital camera, or anything that would benefit from the ability to transfer information faster, should consider getting a higher "class" card, like a 6 or 8. They are only a little bit more expensive usually, but the speed difference CAN be noticeable if your device would be helped by additional transfer speed. Sorry if I repeated myself a bit, but I wanted to be clear and stress those points. But for a general purpose MicroSDHC card, it definitely is exactly what I was hoping for. One thing to note, it DOES come with an adapter, but NOT a High Capacity adapter. This won't make a difference if you're running Windows Vista, or can hook the device (with the card inside) directly to the computer. If you don't and can't, however, you might want to look into getting a card reader that reads HC cards, or just get a different product that DOES come with a High Capacity READER (they do exist, and ARE packaged with cards...again, usually just a bit more expensive). I hope this review helps answer any questions that weren't answered by the description; they cover the things I personally wasn't sure about when I ordered. Definitely a good product, though, so don't let the block-o-text scare you off.

Micro SD's are more popular now because of the PDA explosion (e.g. Blackberry, Motorola Moto Q9h, Samsung Black Jack, etc.).I haven't seen a Micro SD be used for a digital camera device yet, so I'll guess it's mostly these PDA type devices that they are being purchased for.Buyer beware! If your PDA device specifically states it can only support up to 2gb in the expansion memory slot, then anything over that size may not work.I bought this 4gb Kingston Micro SD with adapter for a Motorola Moto Q9h (AT&T), and it failed to recognize the Micro SD. It detected it, and let me know how much memory was there, but it would give me an error and would NOT allow me to save to it, or open the file I had on it. So, I sent the Moto Q9h back and replaced with a Blackberry Curve 8300, which also stated that it had an expansion slot which would support up to a 2gb Micro SD. However, I tested it with another Blackberry 8300 model and it worked.So, make sure that the Micro SD you're buying will work with your device. The safest bet is to go into the store and try it on your device.The other thing, Motorola has failed in all aspects to compete in the PDA phone market. If you're thinking of buying a PDA phone device, avoid the Motorola. It failed in many way than just the expansion slot not working. I think the Windows Mobile OS was the other problem.

Kingston's 4 GB microSDHC Class 4 Flash Memory Card is the perfect addition to your microSDHC-compatible device. After adding it to my Blackberry Tour, the card has given me plenty of space to store my media and pictures.Performance: While the Blackberry is nowhere near as demanding from a read/write speed standpoint as a legitimate digital camera is, this card performs just fine in terms of expanding the space available to saving media.Fit and Finish: Perfect.Support: Kingston backs their memory products up with a Lifetime Warranty so should something go wrong, which is incredibly unlikely, they will be there to provide any necessary support.Amazon's Frustration-Free Packaging: This could be the best attribute of this purchase. Amazon has really gotten packaging right with their new Frustration-Free option. Gone are the horrendous clamshell packages manufacturers so frequently use for products like this. In addition, the new packaging is far more ecologically friendly which is nice as well. I am very happy Amazon has taken strides forward in improving not only the shopping experience online, but also the experience once a product arrives in the purchaser's home.Recommendation: If you need a microSDHC card, this is a perfect option.
