"An excellent device, with a few shortcomings"
These days USB flash drives are the easiest way to move data back and forth, and you never know when one might come in handy, so I always carry one with me wherever I go. That said, a small form-factor helps a great deal in not having this be an inconvenience.

I've used both this KingMax Super Stick and another gumstick-style drive from Transcend which was similar. These drives achieve their small size by using a double-sized PCB construction that allows them to be made about half the height of a female USB port (~2.2mm). The encapsulated PCB on which the USB contacts are formed is glued to a thin plastic casing that provides the lanyard hole.

The PCB is encapsulated in a layered plastic that almost looks like it was surface injected, but I believe it actually uses adhesive. Whatever the case, the circuit components are sealed very tightly, making it extremely well-protected from the elements. I'm not one to tempt fate, but mine has survived several accidental dips in the kitchen sink. Standard flash drives use a single-sided process coupled with a snap-on plastic casing, which means all the components are exposed inside - never let these drives anywhere near water!

The tight sealing of this drive also insulates its components, making them more sensitive to heat issues. The designers have tuned the drive to operate without risk of overheating. So, the drive is noticeably slower than typical models. I haven't bothered to do a speed benchmark, but transferring a few hundred megs takes about a minute or two. This is acceptable to me, but I wouldn't use it for Vista Boost or anything speed-sensitive.

Although the PCB itself is constructed solidly and I could see it lasting for years, the outer plastic shell is not built as well. The adhesive has begun to wear on both my gumstick-drives so that you can see the PCB pulling away from the casing if you press on it a certain way. The worst part of the shell is that only a sliver of plastic separates the lanyard hole from the edge. I prefer attaching the drives to a small key-chain ring, and the plastic adjacent to the lanyard hole on both my drives broke within a few months from the pressure on them.

All in all, the small-size of this drive is a wonderful thing, and I will be getting more in the near future. The poor durability of the outer casing is its biggest annoyance, but with USB memory this cheap these days, it's worth it to be able to keep one unnoticed in my pocket at all times.

"Ignore the nay sayers"
I've had this product for about three weeks and it still works great. It's so much faster than my old thumb drive too. I tested it on my computer using hdparm and I have read speeds at about 27.25 MB/sec.

"Just took it out of the dryer...."
I bought this drive while I deployed to Iraq. I needed something durable and it stood up the sand and the heat without an issue. However, I wondered if it was really washer and dryer safe. After a trip, I returned home and put my clothes in the washer, unknown to me my this flash drive was in a pocket and when I took it out of the dryer (moments ago) I plugged it in and it worked without a hitch. I love this drive. It is worth every cent.

"Simple, Easy, & Tiny"
This works exactly like I'd expect a flash drive to work. I have a few other ones that come with own built-in softwares that try to add things in like games - they take longer to initialize when all you want to do is transfer files. This is simple, easy to use, and initializes very quickly. Just plug it in and transfer files back and forth! It also comes with a little, rubber carrying case, which is convenient as well. I have many flash drives and definitely recommend this over the others I've tried.

"Beware!"
The tip broke off. Kingmax wants me to pay shipping to and include $10 for return postage. According to the RMA request they want it shipped via UPS or FedEx. It will cost more to replace it under warranty than it cost to buy it. Unfortunately I bought several. Also, they are NOT high speed by any stretch of the imagination.
