Pros: Speed is pretty good. Samsung Magician gave me a 143 MB/s read and 55 write. It was expected so I'm happy. Bought it primarily to copy over video and screenshots from my PS4 so I can leave more hard drive space for games. Fits perfectly and is unobtrusive.

Cons: This isn't a con for me because I'm not traveling with it but It's very small. If you tend to lose things, you probably will. As others have said it does get hot. It doesn't seem out of the ordinary for high speed memory. I just think there isn't much there to dissipate the heat.

Other Thoughts: I would say $31 bucks is a good deal for the physical size. BB has a 130 MB/s version for $119 but were sold out as of 4/17/2016.

I recommend it if you don't think you'll lose it. If not a larger one might be better. If you don't want to upgrade your PS4 hard drive just yet and you have a lot of media saved, this might be for you.

Pros: Look you must of sent me the wrong one because it doesn't read up to 150 mbs

Cons: Fix

Other Thoughts: I want an email so we can decide how we can handle this tokoskater123@aol.com

Pros: it is very portable, the size of the device was the main purpose of my purchase

Cons: the advertised storage capacity is 128GB but the available size is 115 GB now I wonder where 13 GB of storage when to? I used it in a usb 3.0 port and also in a usb 2.0 port, the transfer rate in both of the ports did not went above 20 MB/s. converted to Mb, it should be 8bits per every Byte, which is 20 * 8 = 160 Mbps. being aware of this, why is the usb 3.0 port or viceversa ( the 2.0 port) transfering at the same speed?

Other Thoughts: Still, regardless of those minor cons, it's very addictive to have such amount of storage in that tiny size.

Pros: It is small, I can leave it plugged in my laptop all the time
Capacity is great
When it wants the transfer speed is amazing

Cons: The transfer speed is really slow 75% of the time, it starts transfering files very fast, but usually after 30 seconds the speed drops to almost nothing and near the end of every transfer there is 30 seconds to 1 minute of nothing happening and some unresponsiveness. It also gets very hot.

Other Thoughts: Not sure if I will keep it

Pros: Large capacity, tiny, fast and secure.

Cons: None

Pros: Small and unnoticed being mounted. Very good price for 128GB

Cons: It indeed gets very hot. It can actually burn your skin after you move 10GB size and make contact of your skin with it.

Pros: This product even though it has one job to do and that is to hold data in it has came in handy very much for a gamer that needs allot of space for purchased games on the Wii U... it also comes in handy so that you can encrypt any files so that if you want to be the only one to see them you can. its a mass storage device so do with it what you like.

Cons: NONE really except that the device gets really really hot while using it I dont know if its because of a certain USB slot that has a powerboost or what all I know is take it out sometimes if you feel concerned about it becoming fried.

Other Thoughts: Just Remember that its tiny and its very capable of handling allot of data. and like most cards as in other companys I only trust Sandisk because they are a #1 Brand Storage company.

Pros: Tiny. Hides on Keychain

Cons: The cap falls off and is lost forever. It's very tiny.

Pros: - Not a fake one like others here stated, tested with multiple sector read/write programs
- fits on keychain
- easy to insert/remove
- TINY!!

Cons: - Not top usb 3.0 speeds, but does get tidbit faster than 2.0. (20-30mbs write)

Other Thoughts: I ordered this because I wanted to SMALLEST usb drive possible since it's going on my keychain and hate usb drives that make my pocket look like. ya know..
It fits the bill, and I really mostly only care about capacity and small factor. It's also CHEAP so in reality this is a great deal.

*** For people complaining about how 'hot' it gets. It's fine. I've had usb drives that get this hot. It's no unusual and it doesn't stop working. I can pull it out and it's not a big deal. My gosh people are petty here sometimes.

Pros: -Physical size (used to have another brand 64 GB stick that protruded three times as far.)
-Memory Capacity (At the time I am about to order, can only find one form 128 GB USB stick and it isn't completely on the market.)
-Price. (Thanks NewEgg. Taking advantage of a special, is cost me about 20¢/GB)

Cons: -Why is plastic flange on it so long? It doesn't appear to integral to the functionality, yet stick out a quite a way. Seems like that might make it easier to get caught by a shirt sleeve of something and get pulled out.

Other Thoughts: Running on USB 2 so not experiencing heating problem
