MOSDART 64GB USB Flash Drive 5 Pack, 64 GB Multicolor Multipack USB2.0 Thumb Drives, Swivel Design with LED Light, exFAT Jump Drive Memory Stick for Computers, Data Storage

Work OK - but slow transfer rate.

made sure all 5 worked. One of them was also put under heavy use because one of the PCs gave up, had to zero the usb stick out for memtest, then made a linux installation media out of it, then used the usb stick like that for over a month, and finally installed the system into the hard drive recently. The single usb stick I used is still intact after all of that and Im more than thankful for it

Very inexpensive, but good quality. Sometimes the sneaker net is the only way to transport data, and these USB sticks help enormously. Highly recommended!

I returned the 16GB mosDart USB drives since one memory-stick failed or was defective. Sadly, I found out after a couple of days of work that I lost because the data I had stored there was not accessible.the UBS could not be read and asked “if I want it to initialize it.” Of course that meant erase everything I had stored in it. I retried it again and again, even after I had powered off my computer, re-starting it and I got the same result. I went to check if I could read it in my apple laptop, got the same message, check it in a Toshiba laptop same thing. Tried it in my husbands Apple Tower and also got the same result. In 4 computers your memory-stick could not be read. Accepting to the idea that if I initialize the USB-stick would erase everything, I clicked to initialize it. Now, I got another message saying that the “initializing had FAILED.” In the many years I have been using floopy drives, CDs, memory-stick, flash cards etc. , yes, I may have had maybe a couple of bad floppy drives, even maybe a couple of CD disks. But this is the first time I had a defective memory-stick. Even the free memory-stick we get in conferences have worked fine for us. As you can surely appreciate, I did not want to experiment using the other drives from the package. Maybe it was a “bad-batch.” I purchased your memory-stick because they were less expensive than other name-brands (Patriot, SanDisk etc.). I learned that I better pay more for those name-brands than to have the uncertainty that if, I use the others, they may fail as well. I am working on a deadline with a publisher. How am I going to recover the loss of 2 days of work? after 2-3 days I returned the package with all the drives. I marked BAD or Defective over the bad drive. In addition I included a letter explaining the problem. Hopefully the seller reads it and makes sure that there are no other bad drives in their inventory.

This is the second time I have ordered this product. I was satisfied the first time and this time is absolutely no different. If you need a product that does the job for a great price this is one of the best. The shipping is so quick. You wont be disappointed!

Purchased to distribute a video to family members. 4 of the 5 worked fine, 1 does not read at all. The computer doesnt even see its connected. Still a good price for 4 though :)

Muy bueno solo que cuando le das click derecho para formatearlo dura mucho para abrir.

2019-05-09 UPDATED. Upgrading from 1 to 3 bc of customer service. My testing shows that copying to these sticks and having the Mac enter sleep mode renders the sticks inoperable, and the Mac needs to be restarted. Note that I repeated the same behavior below with a second stick. 2/2 for sleep state resulting in death. +2 stars bc of customer service involvement and attention. Note that as of this update, I am now aware of any resolution nor cause for this behavior. For now, I would advise buyers looking for MacOS use to do so with caution. ORIGINAL: Finally had a reason to use these. and i started to copy over about 16 GB from a microUSB to this stick. Started it, and went to bed. Woke up to some error about a file in use. Could not get the stick to respond. Restarted computer and still could not stick to respond. Tried the mac and a windows computer. Windows yielded the NO MEDIA error. As best I can tell this implies that the hardware controller is no longer functioning. so 0 out of 1 for this set. I think this means I am hard pass on MOSDART. good luck, everybody.

Not useable for my purposes. 2 have failed after format, 2 more can not berecognized after a large data load. Would have returned but waited too long

One of them came with a write protection on it and is useless to me because I can not clear it. I have tried everything google has suggested, even going into the registry, downloading 3rd party tools, using CLI and nothing. Not much I can do with it so its going in the trash. Luckily the rest seem to be working okay but I bought 5 because I needed 5. Edit: The seller not only reached out to me after I left my review but they also sent me a replacement flashdrive. This one works great as do the other 4 I received. I am updating my review to 5 stars for 2 reasons. I now have exactly what I purchased and also the seller went out their way to make sure I was a happy customer. I will definitely purchase these from this point forward. Solid company that values their product and customers. Thank you MosDART, you have gained a loyal customer!
