"Very good offer from Kingston!!"
I don't have any comments out from the normal behavior and basic operation of this good product from Kingston. I'm going to continue purchasing and this time 5 to my frineds. I installed all my portable apps and i had no problems.

"Improved!"
My son needed a flash drive for the eight grade. Since I was totally happy with my Kingston Data Traveler I (Generation I), I wanted to buy my son the very same flash drive. That's when I saw there was a Generation II, so I bought it for my son. There's no pesky cover for my son to lose. And it also seems a lot faster, too.

"flimsy but functional"
I'm a bit disappointed in how flimsy this thumbdrive feels. It has a rattling lightweight plastic case that feels like it could snap in half if handled too roughly. Large capacity drives have gotten so cheap it's amazing, there are several drives to choose from at this price point. This one feels like a toy but performs just fine. I haven't tried to benchmark it yet and no matter how it does I'm not sure I'd recommend it to anyone. It just feels too lightweight and breakable and there is no activity light.

I got the 4GB (fried egg color) for myself and a blue 8GB for my wife. They are identical except for the color and capacity. Kingston is a trusted brand so I'm not worried about their performance but I am concerned about durability.

All that being said, I have to admit I kind of like the fact that this drive is unique in its toy-like look and feel. As a previous reviewer said, "it looks like you got it in a gum machine" - excellent way to describe it.

edited to add: sorry, there actually is an activity light, very dim but once you realize it's there its nice to have. It is under the white plastic and barely shines through it, in the front near the USB connector.

"paying attention to the costumer"
Somehow my package was returned and they got in touch with my the same moment to advise me they were sending it again. I got my package a few days latter and they took all the responsabilities. they showed respect for the costumer and i'd buy with them again.

"Nice, but does have 1 flaw"
High Speed Kingston USB 2.0 Flash Drive Data Traveler 100 - 4GB (DT100/4GB) The product link description is close but, not exact. It is a Kingston DataTraveler I Generation 2 - 4 GB USB 2.0 Flash Drive DTIG2/4GB (Yellow).
Kingston makes great products, and for typical computer use for backing up files, and transfering data, ect. It works perfectly.
However, because of it's shape - the body is bigger and longer than most that I've used, so when I try to insert it into my Canon MP470 to print files, it just won't fit. The male end of the drive is just too short to do it. It is a minor pain, but I've got other drives I can use for doing that so it's not that big of a deal.
Otherwise, for the price it's a real deal esp. @ 4GB. I have no problem at all recommending this at all. Buy it, you won't be disappointed.
