Pros: Have a nice design and his real capacity is 3,75gb (tested with h2testw, as promised).
Is small and really handy compared to some usb devices you can buy, his size is almost 1/2 size of one of your fingers.

Cons: The size, is really SMALL, and the case for save it´s very tight, so the extraction of the drive inserted is a bit hard. Other thing to know is the correct position to insert it on one USB port, so take care with this.

Other Thoughts: The speed of this drive is normal and I don´t saw weird things when I transfered some files to the drive, so for me this drive is very good.
Other thing for consideration is the force you put for extract and insert this drive.

Bottomline: I like this drive and it´s a good purchase for me. I recommend it!^-^

Pros: The drives are really tiny, any thinner and they wouldn't fit into the usb socket. It measures to the claimed 4gb capacity and looks nearly identical to the pictured item. It also comes in a retail packaging and looks professional. My silicon cover is blue, not pink like the one in the DX pic and the cover is a good idea for protecting it in a bag or pencil case etc.

Cons: Very small size could make it easy to lose. Size could also make it vulnerable to being snapped off or broken while in the USB port.

Other Thoughts: I think this is great for the price, not much more than most other usb sticks of the same capacity. I have just ordered a second one for my wife.

Bottomline: Very hard to beat if you want a usb stick that you can take anywhere and slip into a pocket or wallet etc. Recommended.

Pros: This is so small that it's very hard to remember that it is a flash drive on your desk and not just a piece of paper or gum you left behind. I'm afraid to lose it but so far I have not. Works at a good speed and there are no problems putting it into the USB port (odd at first but then you get used to it). I can take this anywhere I go and it holds a huge amount of my files.

Cons: I like the case but it is pink. I just think it’s a bit too pink to have on my keychain or my belt loop. It's not actually 4 GB; it's 3.76 GB (4,042,981,376 bytes). I know they are never exactly the capacity they say they are but it was a bit farther away from 4GB then I thought it would be.

Other Thoughts: If they offered other cases here in a different color I would buy it. Some flash drives/memory sticks have a small built in LED to see if it is reading or writing and this one dose not have it; not that it matters or not. It seems strong so it will not snap in two, and it has a hole to put it on a keychain or other holder.

Bottomline: It's too small to pass up. Not just the fact that it is the smallest I have seen but it holds 4GB!
