VICFUN10 Pack 4GB USB Flash Drives 4GB USB Memory Sticks USB 2.0-Black

Worked as anticipated

I'll start by saying that I was purchasing to a price point. I needed 50 drives to distribute football season photos to our kids on the team. These were the best price I could find. I saved roughly .50 per unit over the cheapest name brand drives. That being said, you get what you pay for. These types of flash drives are generally marketed to the promotional katchka business, where a buyer will buy 1000+ at a shot and have them printed or engraved for promotional giveaways. As such, speed, quality and reliability are less important than price. Of 50 units purchased, 2 were doa. Another 4 failed after initially loading okay, but on a subsequent rewrite. I expect more will have failed once all of the kids take them home and try to use them. Just based on the 6 that I couldn't give out, I've already lost more than half of the savings I made over the name brand memory. But the real disappointment in these devices was the write speeds I was seeing as I tried to write to them. I was writing 3 GB of data to each of these drives. I was seeing write speeds as low as 100kb/sec, or 40 minutes per drive!. Others would write at up to 2MB/sec, but there was no rhyme or reason to how each would perform. I was fortunate to have access to a number of quality PC's on which to write these, and could bank drives 4 to a machine to write, I was able to achieve my intended purpose, but in the future I will opt for the pricier name brand drives. Between the 12% failure rate and the the slow write speeds, the aggravation was not worth the savings.

We came in a nice neat Packaging, they look fine I have not had the chance to actually see what their capacities are, we use them to store short videos on to give to our customers. Have not had one failed but I've only tried one so far. Good value for the money so far.

I buy these regularly and overall I like them. (although 1 in the bunch usually does not work) They are a great price point for giving out to friends and basic needs.

I think these are good purchase. The size is good for storing music and photos I need to be portable. The price is very good also for 10 flash drives. Would recommend them to others.

Easy to use

Flash drive worked well. Not the fastest, but not the slowest that I've used. So far, no defective flash drives in numerous orders (of 10 each) of the 4GB ones. I've used the 8GB and 10GB drives, and have been pleased with those also.

Have used these drives before and never experienced a failed drive.
