I purchased this with hopes it would boost my laptop that's around 9 years old. Wasn't disappointed! My laptop has a network card with 802.11b at 50mpbs near the router and up to 11mbps away from the router. The network card was very easy to install and, after testing, fires out a 802.11ac signal at 240mbps far away from the router. Going to test to see what it is near the router.

Doesn't automatically connect to WiFi, have to enable my connection every time I turn on the laptop.

Very neat little adapter. Recommend it for older laptops.

Small. Does not need any drivers installed under Windows.

Expensive. Work poorly.

I was in the store looking for a good quality USB wifi adapter. I did not need the smallest one, but I bought this one even though the assistant there told me I should just get a cheaper one. I wanted a good quality one, thinking this one must be better if it costs more. But it never really worked very well, giving very poor throughput and connectivity would sometimes go down. I have bought some Wireless-N 300 Mbps USB wifi adapters on ebay for like $4, and hey, they work great! They are somewhat bigger than this one, but work, and really cheap. So I would say, only buy this one if you absolutely must have THE smallest one possible (maybe for a laptop you carry around, but replacing the wifi card in a laptop is cheap and easy). If not, then you are paying extra for nothing.

Bought 10 of these for a small office environment in a concrete building where the office space was spread over three rooms. I was worried that because of the building, that the signal wouldn't be very strong. Granted, I have enterprise-grade WiFi in the building, but these adapters were fantastic in every machine. Easy to install, no muss, no fuss.

None

Would recommend to anyone if they needed a small WiFi adapter without an external antenna.

I regret buying it and I couldnt get it back to store because I lost the receipt. The worst wifi adapter.
