Summary: After buying one adapter that wasn't compatible with Windows 8.1, I looked around and found this. With Prime, it felt like a steal for $10 when the usual price was $80. I'm not entirely sure if mine was defective, or if this product is generally bad. 3 stars for the benefit of the doubt.
Works okay. Did not increase performance at all, though.

Summary: I bought it and a wireless N router to give me better coverage in my modest home. It was an awkward size and didn't increase performance even a little bit. Somewhat disappointed but it does work. Spend the extra and get one of the smaller non-draft N USB adapters.
Summary: The D-Link DWA-140 works OK but I was expecting better results. The signal strength is acceptable but considering that I'm paring it with a D-Link N+300 router, I was expecting better results.
Summary: I could not connect to a newer DLINK rounter (DAP-2553) using Windows XP (32-bit) with windows built-in wireless configuration software. I had to install DLINK's software (not just the driver) in order to connect.
Summary: I was able to use my clunky old desktop wireless with this device. It does seem to have a little lag but not annoyingly so. It allowed me to put my computer anywhere I wanted instead of being tethered to a router.
Summary: At the time that I'm writing this review, the D-Link DWA-140 adaptor is available from multiple vendors. Amazon is selling it for $49, so you might want to buy that one instead of buying it from this reseller. Compare the price on: D-Link DWA-140 RangeBooster Draft 802.11n Wireless USB Adapter
Excerpt: The adapter does its job, but still getting low connectivity. I thought perhaps this would be the solution to getting a range extender. B & H is great! [...]. For any future needs, I would not hesitate using them again
"RangeBooster" is a lie, just average, don't pay extra.

Summary: All tried so far so called "dual bend" and "RangeBooster" adapters perform worse than simple N or even G adapters. So don't spend extra money on this advertised c... More expensive ones have lower range and average speed in real public wireless networks.
Pros: Works - sends and receives signals. D-Link reputation. Other brands even worse.
Cons: Lower range than my old D-Link DWA-125 (N, 150 Mbs) for less than 30 bucks, so "RangeBooster" is a fraudulent promo. - 2 eggs. Real tested max web speed was about the same ~ 65 Mbs/sec download. So no real speed improvement.
