KOOTION 10 Pack 4GB Flash Drive 4gb USB 2.0 Flash Drives USB Drive Jump Drive Bulk Thumb Drive Swivel Memory Stick Black

UPDATE: Found out the things seem to work a whole lot better if you re-format them as exfat (extended FAT.) Maybe some of the people who own USB flash drives from other companies got them formatted as exfat and didnt know? Anyway, I need these as I said below, and didnt realize they were formatted as FAT32; once I re-formatted them they perform as expected. --Original review-- 761 Kb/Sec copying 15,000 files from an 8.1 GB ISO. Bought these because the Kootion 8GB were too small (have been reading that the Kootion 32GB are slow and also unreliable.) Buyer beware! Thought these would be helpful, but NOT if they are so slow!!!!!! Maybe the company would consider fixing this and sending me some that actually perform better? ;)

With these flash drives I add a short lanyard to add a touch of color and value added when I deliver my products to my customers

Overview: As described. Experience: Have had no issues with storage or transfer times, Very cost effective. I preferer retractable type but flip is fine for most uses. The flip cover is flat and smooth so you can easily label or write on it. Standard lanyard attachment as well. Best bang for the buck I have found without buying in bulk.

good storage device

So far, so good .... have had for two months and used four of the ten without problems. It is getting harder to find 1GB USB drives for a fair price - but they are perfect for music for plugging into my vehicle or just attach to my computer to hear certain genre ... 1GB is the perfect size. Easy to use and simply to open and close - just slide the sleeve around the USB. The speed of transfer is NOT fast - but acceptable. I havent had any problem with the cover coming free or detaching (someone apparently did). The sleeve is blank and easy to write on. It had no logo on either side (like the picture demonstrated). I also use them for transferring multiple pdfs and docx files of active projects as well as for transferring files between machines. Although limited to 1 GB (by choice), they do the job and work well for transporting files.

These are cool design and hold a ton of data. But...they are not entirely as described in that they DO NOT fit on a keyring. The loop at the end of it was made too small for a keyring and the tang will break if you force it. Other than that, they a really nice.

Not my favorite form factor for a flash drive, I like a snap on cap, but I knew that going in, so no complaints. Having had problems with flash drives in the past I did a disk check on all 10, then a quick format just to make sure they would work on my system and they came out gold, no issues. At this price when Ive giving someone pictures or whatever, I can just give them a flash drive, not burn a bunch of CDs or a few DVDs and hope they have a optical drive. Im cheap, but for $2.50 each I can give them away. Only reservation is there was no speed class noted like there usually is with SD cards so I dont know if theyre fast or slow.

Works good for copying data for use later or elsewhere

I had some trouble at first. I put mp3 music on them to play in my car. AT FIRST every time I would turn off the car, the music would start with Track 1! (turning off and then back on the radio the music would restart where I left off. I checked the formatting which was FAT32 which I needed. What I discovered was that not all the drives had the same format SEGMENT SIZE. Once I reformatted the drives with the DEFAULT segment size, the flash drives with mp3s worked perfectly in my car (re-start where I left off when I turned off the car)

Ive been using these as give aways for images and information patients can take with them to other physicians. Working fine so far
