I am an owner of 4 cases for my Xiaomi Redmi Note 3 but the worst one I have is the Aluminum Metal Bumper With PC-Mirror Back Cover For Xiaomi Redmi Note 3. I had bought it from eBay India for Rs. 230.

It is a very thick bumper case. It is so big that there are empty spaces which can be seen on the charging port and headphone jack.

The main reasons I am writing this review is the issue with mobile and wifi network I faced when I was using this case. As soon as this case was put on, I noticed a significant drop in mobile network signal and wifi signal. Usually, the wifi drop was more than 50%, which is too much. I stopped getting network even in areas where I used to get a good network.

This is a good case only for protection but what is the point of such kind of case if you do not get a good mobile or wifi signal. Watch the video below to see the issue live.
