Enfain 2GB Credit Card USB Flash Drive - Pack of 10 - Gold

This is a review of the Enfain 10 piece business card USB stick pack, 8GB.They arrived neatly packaged in a box of ten, each individually wrapped. Each is about the size of a business card, made of hard white plastic and slightly thicker than a credit card. The USB connector swivels out of the body of the card and the mechanism seems fairly tough.In use, I didn't have any compatibility problems. Pop the connector out, insert it into your PC/laptop and you should be all set to transfer data to/from it. It is, unfortunately, USB 2.0 only, so speed is not brilliant. I did a few runs with DiskSpeedTest and saw average reads of around 28MB/s and writes of just under 8MB/s. Not terrible, but certainly far below USB 3.0 and it'll take a while to fill the full 8GB! These cards are definitely not speed demons, that's for sure.They're great for giving out to clients with demos, particularly if you brand the one side. They are quite pricey though (even the smallest 1GB model is just under $2.50), so you wouldn't be doing this on a large scale! They're great to keep in your wallet or purse though, and the hard plastic should keep it safe.Pros:+ Great for handing out with demos or for marketing purposes+ Convenient to keep in your wallet/purse+ Tough plastic exteriorCons:- Only USB 2.0Overall, this is a neat flash drive. They can be used both to give to clients as a demo/marketing device but they're equally good to keep in your wallet/purse. It's a pity that they're USB 2.0 though - speeds suffer as a result.

I was really excited to obtain these cards as a giveaway for an event. Unfortunately, I discovered they don't fit into a standard USB port - the plastic surrounding the USB connector is a little too wide, and it simply doesn't fit at all into most laptops in our office. On the Surface Pro 3, where the metal exactly surrounds the USB port, it's not even close. On others, it gets in the port, but it's a tight fit and makes people nervous.As such, we can't give these out to customers. And unfortunately, we only discovered they don't fit when we went to load them with data after we removed them from the packaging, so we're out a pretty substantial amount of money.The USB key itself can be peeled off of the card base. It doesn't fit, either (at that point, it's too thin to stay in the port instead of too wide), but we're going to experiment with filing them down or gluing them to some card stock to see if we can make these work and salvage our investment.

I thought these would be great to give clients as a gift. Problem is, they do not work in all computers, and some of them we just could not get to work. I ended up giving them away to family members. Most of them threw them away. Not a quality product. Buy something more reliable.

I have bought a serious amount of these. I have been really happy with them. However recently (Oct 2017) there is a really high failure rate. As in they mostly stop working before I have finished copying the files across. They just die.Enfain had the decency to send an email to ensure I am happy, although they never respond to the email. Several times....

Cool little USB Business Cards. We used them as our Company Christmas Cards this year and they were a huge hit. We ordered 4 batches of 10 and did not have 1 bad card. I was impressed. Considering these are marketed as 'throw-away' usb cards, the quality is fantastic. We have had stories from our clients of passing them around and several people using them and they are still going strong so they have some longevity as well. They came formatted and ready to go so it only took a few minutes to apply our label, load the card and send them on their way. Highly Recommended!

Very compact and unique USB flash drive. I needed to send a legal document in the mail and this worked perfectly. I like the slim design so much I've also used them to back up other important documents and placed in a small fire safe. Will fit easily in my wallet if necessary when I'm traveling.Easy to use, fit USB port on Macbook Pro and didn't need to reformat.

Excellent alternative to CDs when providing a large data file in a small envelope or holder, fits in a business card holder. Won't get lost as easily as a normal "finger drive". Room for a company label for swag.

Interesting and excellent product. They worked perfectly with one caveat - they do not fit into most of the USB ports on desktop computers because the large card surface gets in the way. If you are using them as a promotion as I am you might want to re-think your choice as we don't want to annoy a prospective customer by giving them a memory stick they can't conveniently use.
