16GB USB Flash Drive Bulk Pack of 10 USB Sticks 2.0 Swivel Memoy Stick 16 GB Metal Value Multipack Pendrive Portable U Disk Black Stylish Thumb Drives with Ropes for File Transfer or Share

I bought these primarily as backup drives as I'll be working away from home for a while and wanted a 7-day backup pattern. These fit the bill perfectly, with a couple to spare!One slight issue was that the keychain colours didn't exactly match all the drive colours - what a problem :).

Given it 4stars as it's too soon after getting these to get a proper idea on how good they are or how long they last. Update / I have used 4 of these so far and 2 of these malfunctioned so on this ratio I'm downrating these to 2 stars , I don't think I would buy these again

Review of Kepmem USB Stick 64GB Bulk Pack of 10 (Amazon ASIN B09D3QK71Y)I tried the first few of these and they ALL failed.I regularly use the well known branded USB Memory Sticks and haven't had any problems, before or after trying to use these Kepmem Branded ones.Therefore it's not my setup, it is this product that is at fault.I decided to buy these solely for non-critical uses, the other product reviews being reasonably fair given the price; but the failure rate for me has been 100% so far, and I'm not wasting any more time trying out any more of them.Typically, after copying a few videos to the memory stick, Windows will, fairly soon report that it has found errors and then offers to repair the Kepmem 64 GB stick (image #1).Then, after using the drive after the repair, Windows displays a message that it cannot repair the Kepmem 64 GB memory stick (image #2).Be careful in how you interpret my third image - it's just a reading of whatever descriptive information is stored in the drive's firmware.I've tried to use a few of these Kepmem memory sticks (64 GB) over a week or so, without any success.I've wasted too much of my time trying these memory sticks, each one several times over after each repair, only to find that they continued to fail.I am returning these to Amazon.If you want to buy these to try them out, let's hope it's just inferior ie. very cheap (micro)electronics that has been used in their manufacturing and as a consequence you will end up doing their quality checks for them - it's your time and make sure you only use them for non-critical storage.Also, it would be a good idea to perform a full (slow) format before use (NB. Remember to disconect any other USB storage devices first in case you are distracted).If you wanted to actually test your received memory sticks then you can use these freely available tools, each one has their own advantages...H2testw (good but slow)Flash Drive/Card Tester PortableFakeFlashTestRMPrepUSBI didn't get as far as using these tools, I just gave up with the 100% falure rate I had initially experienced.I continue to use the popular "big name" brands without any problems at all.Remember I bought the large capacity (64 GB) memory sticks branded KepmemGeneral Tip -ASIN is a unique serial number assigned by Amazon to each individual product, you can enter it into the Amazon search box and guarantee that the correct variation will be selected and displayed on the product page that you arrive at, it's really usefull when there are many different variations/products on the same Amazon page.

No

Good quality

I am using these to store music and would be a nice touch if they had someway of writting on them so I could marj then with what it is yes I can use stickers but other than that no issues witht them but not used them all yet

Needed to connect with my cars info system. Worked exactly as required. Feel well made. Connecting lanyard was a little fiddly but with a little patience worked well.

So easy to use and store
