[Q]: This Roocase is the best , great quality product, I love how you can take it out to hold it, then when you put it away in its zipperd case it's very well protected. I bought one last year for my kindle fire. JUST LOVE IT
[A]: Positive Review

[Q]: Worked fine for a year, although the signal was never as strong as my Macbook Air. But then it suddenly broke slightly after a year, just stopped functioning entirely. I tried reinstalling the driver, but that didn't work. I think it's worth it to invest in a better adapter.
[A]: Negative Review

[Q]: I've bought this keyboard for my Nexus 7 and it is such a good keyboard that I've end up using it with my laptop and even my phone.<br />It's well sized and the keys are very comfortable.<br />The only defect is that it is a bit expensive.
