This review is from: SAMSUNG Pro 64GB microSDXC Flash Card Model MB-MGCGB/AM
Pros: -fast transfer speeds
-when used with a USB 3 card reader that's plugged into a USB 3 port, you will enjoy fast file transfers
-ideal card for buggy, issue-prone GoPro3 Black camera
Other Thoughts: GoPro3 Black is quite famous for having/creating memory card issues. It even ruins them. But this card solves all that. Any other trouble you encounter can probably be blamed on your GoPro, not the nice Samsung memory card.
Have you ever had your GoPro card go "corrupt", with all the irreplaceable GoPro files on it becoming suddenly unreadable?
Here's how to solve the dreaded "you must format this card before using it" message that often pops up when you plug your loaded GoPro3 card into your PC and it refuse to read it.
Don't worry, your files are still on the card! So by all means don't reformat it!
Do you know how to access the run command on your PC?
It's available on the Start menu. Or if it's not seen there just type "run" in the Start Menu's little search box and it should be the first answer returned at the very top of the list.
Click on it to open the "Run" command.
Now type "cmd" (for "command") and click "OK".
That will open the command prompt.
Now, before you can really begin fixing things, you must determine which drive letter your PC has assigned to your GoPro3 card. For this quick tutorial, let's assume the drive letter of the GoPro card is "E". In actuality, it might be a different letter for you. But we'll use "E" in this example.
1. To simply "check" the card for errors, type this into the run command line, exactly as written below:
2. now hit "Enter"
3. Now your PC quickly checks the card for errors, and shows you the results.
--But this next step takes care of the whole deal in one move.--
4. To check "AND fix" the errors in one simple step, type this into the run command line, exactly as written below:
chkdsk /f E:
5. Click "Enter"
6. You're done.
That should fix all the card's errors, and make your valuable GoPro recordings accessible again!
The GoPro is to blame for messing things up, and making it so the card cannot be read by your PC. But the recordings themselves are not affected. This fix repairs what's wrong, and solves the problem.
Once fixed, the computer should instantly discover the newly corrected card, and an auto-play dialog box should appear!
Again, just be sure that you use the correct drive letter of your GoPro card. The example we used was "E", but your drive letter may be different. So just replace the "E" with correct letter.
If you use this quality Samsung card in Your GoPro, the above fix should work every time. Other cards can get toasted by a GoPro, or so I've very often read. Even the exact brand and model of flash card GoPro recommends and sells on their website, gets easily toasted (ruined) by a GoPro.
...whereas this Samsung seems to be bullet-proof.
This card has eliminated all my GoPro3 Black issues, because it's always instantly recoverable, by following the simple step(s) I've outlined above.
Hope this helps someone.
Bottom line? Great card.
Pros: Faster than any "USB 2" type card reader I've ever used.
You'll spend less time waiting on file transfers.
Small, light, and convenient.
Cons: None I can think of.
Other Thoughts: This thing works much faster than my USB 2 version of the same type of item from another brand. Though I was happy with my old USB 2 reader, I still wondered if a USB 3 reader could really save me some time. So I bought this find out.
I use it primarily it with the 64GB S*msung (MB-MGCGB/AM) MicroSDXC Flash Card from my GoPro3 Black. It did indeed speed things way up for me. In fact, it's roughly twice as fast as the I*GEAR (GFR209) model it replaced. When dumping up to 64GB of GoPro files to my computer's HD for editing, that's a real time saver. Of course, if you use it with slow rated flash cards, you might not experience any improvement over your old setup. Likewise, if you plug it into an old USB 2 port, you might not experience any improvement over your old setup. For example, when I tested it while plugged into a USB 2 port, it yielded the exact same transfer speeds as my old USB 2 reader using the same flash card. But that's to be expected.
Here's how to get the most out of it:
1. Use fast rated cards
2. Plug it into a USB 3 port
3. You should then enjoy a marked improvement in transfer speeds over USB 2 readers.
This review is from: SCOSCHE sunVOLT Black 1500 mAh Solar Powered Backup Battery and Charger SOLBAT2
Pros: Takes my iPhone 4s from near dead to over 50% charged. Doesn't seem to charge most devices completely, but will charge them enough to make a big difference.
Can (might, depending on the device) add hours to the run time of your device.
Convenient USB port for plugging in almost anything that needs to be charged. Of course, you'll also need to utilize the USB charging cable that came with whatever device you're attempting to charge.
Cons: Being just 1500 mAh, it can't fully charge an iPhone.
Other Thoughts: -I have never attempting to use (or even to test) the solar charging capabilities.
-I paid only 13 bucks including free shipping (brand new), at a site other than newegg. Whereas newegg has it priced at 45 bucks right now! Pay less than 20, or don't buy it.
-I gave it 4 strong eggs based in part on the price I paid, at just 13 bucks shipped.
-It's either in (green led) export-charge mode, or (red led) self-recharge mode, or (no led) inactive. It cannot do two functions at once.
-Makes my extended nature/biking outings less risky phone battery-wise. Instead of coming home on empty, I come home with a comfortable cushion left in the tank.
-Keep it topped off, and bring it with you when you go out.
