First off, three stars on my scale means pretty decent. Am not going to waste your time with an extra elaborate review. One of the video reviews here should tell you that it fits well and does not fall off unless you are performing a circus act or riding a twisted roller coaster. The weight is also perfect. However, you need to make sure you do not bury your cellphone in your pockets under lot of other things. It hurts the reception. The battery back up is not the best, and wind is the biggest problem. IF YOU LIVE IN OKLAHOMA DO NOT BUY IT. If it gets windy, the other person can hardly hear anything.
