Pros: Dual-Band capabilities, bandwidth, range, size, simplicity and price
Cons: Apparently not compatible with Win8.1
This small little device really does a great job at an affordable price.
What I love is the fact that the device comes with 5GHZ support. It does unfortunately only have a bandwidth of 300mbps, which is a shame as I like having the ability to run 5ghz at 450mbps. With that said, at the cheap price and the convenience, I find the USB adapter excellent.
At short range this little device does an excellent job and what surprised me is that at distance (over 10m from the router, with walls in-between) it had an excellent range. This is where most adapters would fail and have failed me - and thus it was nice to see that this adapter performed well at range too.
I should note that the speeds were slightly effected (ie I was getting 300mbps at 2m from the router and then getting 80mbps at that 10m range).
This however didn't really effect my speeds that much - I went from 38 down & 9 up to 32 down 8 up. This is to be expected though and I've seen this with every wireless device that's been connected at that range.
Driver installation was easy for me and I had absolutely no problems on Windows 7. I cannot comment on other OSs but it seems that it doesn't run on Win8.1 (as mentioned in the AmazonUK title).
The software that's bundled with it as well, works great too - and I had no problems with it.
Overall, the adapter is excellent and I highly suggest it to anyone - especially laptop users.
