This looks great however it cuts your signal by about 20% when it’s on the phone.
Certain cities with strong cell towers like Houston and Tampa this worked great, worth
every penny! However cities like Milwaukee and Chicago this was terrible!!! Every call
was dropped until I removed the case. When it works it’s awsome, however the results
vary from city to city as I traveled. I would not purchase this unit again if I had a chance
because it is worthless in those cities. It’s a great extra battery for watching movies
on an airplane though.
