Great idea but doesn't work very well. Samsung Galaxy S3:

-I connect to my wifi using a really good asus router. Sentiment 9.0

-I often lose connection in locations where previously I had excellent reception. Sentiment 8.0

-it worked great until july this year when it stopped receiving a network signal. Sentiment 7.5

-the samsung exclusive touchwhiz apps were gimmicky at best. Sentiment 9.0

Etc. If it's unbiased I'd guess the errors would average out, though.
