Summary: Connectivity was very good first few minutes but then saw a noticeable decline in connection speed to the point of lost wireless connection. Same result after numerous attempts. Will be returning for refund.
Summary: This product claims to work with the Raspberry Pi 2. I installed it using the latest sable release of the OS, Jessie, and couldn't get this product to work. I read many tutorials online about it, much of it with conflicting information on how to get this to work.
Summary: Didn't really do anything for me. The range I was actually able to use my wifi was still the same. The only difference was that I was able to see that I was "connected" to the wifi from farther out.
