  1. I bought a black case a month ago and so far there haven’t been any issues. Signal amplification is a very good thing to have. I tend to drop calls on my way to work when I drive through the canyon, but I don’t worry about that anymore. Now my co-workers want this case too since I am the only one in the office who doesn’t lose a signal.

  2. I bought the mJoose for my son because he is always running out of battery and hanging out in areas of town with bad reception so he drops calls very often. The case lets him tweet, snap, text, etc. all day. Also, he always answers and stays connected when I call him now. Buying this case was a much better idea than putting a signal booster in his car that would only work when he’s in the car. This case definitely solved 2 problems for me and my son, so I highly recommend the mJoose for anyone and their loved ones.
