Pros
-Low power consumption is perfect for those using it on a raspberry pi since It does not require an externally powered usb hub.
-Small form factor does not block other usb ports.
-Compatible out of the box with the raspberry pi-no additional drivers need to be installed manually.

Cons
-No 5 GHz band support.
-Range is limited even for a 2.4 GHz only adapter-Dont expect to get 150mbps unless you're right next to your router
-While cheap, there are far better alternatives for a few dollars more.

Overall, i would recommend this device if you're planning to build a compact pc and need basic wireless connectivity. DO NOT BUY THIS IS YOU PLAN TO USE IT TO STREAM MEDIA CONTENT AT A DISTANCE GREATER THAN 20 METERS. The transfer speeds are not good enough to get smooth playback or establish a stable enough connection.

A simple, inexpensive fix to the intensely frustrating wifi issues that have plagued my $1700 Surface Pro 3 since purchase 6 months ago. Good god is it nice to have consistent wifi. So basically If you have wifi issues with SP3, it's worth spending the extra $15 on this little guy.

Works okay, during the beginning I was getting very low speeds and terrible wifi signal on my raspberry pi, unplugging it and plugging it back in fixed the issue. The signal is still very poor but now I'm able to stream content from where my router is placed

I purchased this little guy for my Pi, plugged it in, followed some directions I found online to configure it for a static IP address and it works great! It is fast, and keeps a steady connection.

EDIT: Oddly enough, though this card boasts much better signal than my old one it seems to have much worse SPEED. Still functional at least. I'll see soon enough whether it fixes some problems I've had with Cisco access points and edit this review accordingly.

This usb network card works beautifully on Fedora 17 with one minor caveat: you'll have to download the drivers from Realtek's site. They're not included with Fedora by default. That said, this is a huge improvement over my internal adapter which had very serious problems with Linux (it's another wireless card which uses Realtek's rtl8723e drivers which are unfortunately still prototypes). So, if you're a Linux user and you're wondering, these work just fine with Realtek's own drivers. Additionally, if you're not a very advanced user, the drivers aren't as difficult to install as many kernel modules - it's just a matter of running a script provided by Realtek. You need the RTL8192CU drivers from Realtek's site. Be careful not to accidentally get the RTL8192SU drivers the first time around as I did, or the RTL8188CUS drivers.

Additionally, while I can't speak for the Windows drivers, I'd assume they're functional and can certainly vouch for the hardware seeming solid at least.

Seeing as the product doesn't even technically advertise Linux support, this is pretty good. Especially for $13. 5 stars.

Oh, and it's amazingly tiny! You can barely see it sticking out of the USB port and it certainly doesn't get in the way. I have no idea how it even works.

Woks perfectly. Tiny form factor makes me feel like I'm on a brand new laptop! Does get a little warm with heavy streaming but I have not enountered an issue yet with use over 120 minutes streaming a long movie. Arrived quickly. All positive review!

Bought for my Raspberry Pis. I've had issues with the TP-Link adapter shutting off after 1+ day, forcing me to restart my headless Pi devices. I've got one of these adapters on my OctoPi server that drives my 3D printer and it stays up and stable for weeks at a time.

It's also incredibly small - the smallest USB wifi adapter I've ever seen.

There's nothing I can fault with this product. Issues in setting up wifi are commonplace, but that's usually a problem with your platform or software, not the adapter. At this price this is an absolute steal and worth having an extra one in your parts drawer as a backup.
