SANDISK 4GB Micro SDHC Memory Card SDSDQM-004G

Small capability cards are getting more difficult to find, and I wanted to stick with a name brand to breathe a bit of life into my 2 older Roku 4660R devices. If you have an older device, these 4GB MicroSD cards may be just what you need. Now, all my channels are stored locally and open without delay. I put this purchase off for some time since my most frequently used apps were available without delay, but recently subscribed to a few of premium services pushing me more over the local storage limit on the Roku. Now every app is stored locally. BTW, hats off to Roku to be able to swap apps as needed, when you don't have enough storage!I purchased my cards new through MemoryWhiz with bulk packaging; card and adapter in the OEM plastic storage case placed in a small zip bag with a label I assume printed by MemoryWhiz. Both cards were unused (new) and formatted right away and no issue so far.This is a good value considering the other sellers, but for the size of the card you do pay a premium. Perhaps as they are no longer made, difficult to find?

I got this for testing in an embedded application (this will be permanently installed inside a product). It came with an SD adapter and also a download link and password for some sort of mobile application.Since I'm using this as embedded memory, I have no use for the SD adapter or the mobile application so can't comment on them.The card reported to my software that it will work over all voltages available for an HC card so there shouldn't be any compatibility problems.I don't know if it was formatted or had any software on it, I didn't check as my software bulk-erases any card before using it.Have scissors available to get into the package. The link and password are hidden inside the package so if you need it, be sure to look for it.

This is working just fine, but I wanted to leave this for a "generic" 32GB card I bought. Ironically, you can't leave feedback for them, only the ones that work like this, Sandisk, Samsung, Sony, etc. Anyway, if you're shopping you may be looking at them as well because they are cheaper, but here's what I found out:Although a different seller of a cheaper unit refunded my money and told me not to bother returning the Micro SD card, the fact that these cards from this vendor appear to be mostly defective makes me wonder if they make their money off folks that don't bother to apply for a refund or write a review. If only 1 in 10 complain, they can make a ton of money -- even selling them for next to nothing. I've switched to name brand for Micro SD cards. Not worth the hassle. There are defects in manufacturing these -- especially higher capacity, and rather than throwing them out, somehow they make it to vendors who sell them, hoping a few actually work and for the ones that don't, well, the buyers will just throw them away.

I needed a low price 4 GB Micro SD and this was the best. the product is a class 4 and still has a better price than most class 2s (only a few cents more expensive than the cheapest class 2 on Amazon)as shown in the picture and comes with an adapter and a case.It is working just fine for me and if you are not looking for an application on the high speed end such as a camera (in such case go for a class 10) that's a great deal.

The price of these cards doubled over Christmas 2012. But it was a good buy at just over three and a half dollars November 1st. Class four cards don't have transfer speeds to write home about but they work fine in phones and voice recorders. Just don't expect to record 1080p HD video! With capacities up to 32 and 64 gigabytes becoming common, these four gigabyte cards will be outdated soon. (a two gigabyte card costs the same as the four gigabyte) But in the mean time you can sure get allot of music and photos for the money. And by the way, as of this writing (March 14, 2013) if you look you can get an eight gigabyte class four card for a few pennies less than the four gigabyte card. Progress...progress. So the only real reason to get the smaller card is if your device won't accept the larger capacity. Always check your device manufacturer for comparability first.

Worked exactly as expected, very happy!

I like it of course. Just disappointed that it was not emptied of pictures before I got it. Did not appreciate the pics I had to look at while deleting them.

This Micro card is incredibly cheap. I formatted it and then installed it in the phone. One Caveat is don't give the card a volume name when you format it or the phone won't recognize it. I did this the first time and then reformatted it while removing the name and the phone recognized it right away. I moved all photos to it and no problem. Any problem I had was with the fact that my Motorola phone only allows you to move a few things to a storage card like this but that's not this cards fault. All in all I'd say at this price you really can't go wrong. The worst case scenario is that I could use it with the provided adapter in my computer for some extra memory. Once again, you can't go wrong with this.
