Pros: Very small, so it sits very securely in the USB port - I'm not afraid it's going to get knocked out by anything. Was very easy to connect to WIFI (i'm not great with technology but even for me, it was easy) - and the connectivity is excellent - I now have full wifi on my computer at great speeds.

Overall Review: I found a second hand computer for a great price online - never realized it didn't have wifi built in (no wonder it was so cheap), so when I got it, I had to connect with a short (the only one I had on hand) ethernet cable to the modem and router, which meant sitting on the floor, cross legged with computer on a cardboard box. Not good. I looked for ways to connect with wifi - found this Wifi adapter or dongle, and thought I'd try it, not sure how complicated it would be to set up and I was very surprised - just plugged it into the USB port at the back of the computer, followed a few prompts and that was it - made sure I got the correcct wifi password put in - and pooffff! I got the wifi connected signal, I clicked on a website - and couldn't believe how fast it loaded. So now I've been able to move my computer and monitor to an actual desk - probably about 20 feet away from the router - and it's still lightning fast. This is definitely one of the best purchases I've made. I also needed to sync data from the computer to my phone - something I couldn't do before - and it was a breeze. i am SO pleased I did this. It's also a tiny little dongle, so doesn't stick out far at the back, very secure when it's plugged in to the USB port. Very happy.
