If you want to protect your 8125 from pretty much anything a 2 year old can do to it, this is the case. If you want your phone to connect to the cell tower down the road, it might not be. I did some tests when I first got the case, without the case on I saw 4 bars, with the case 3. I repeated this test in several locations and got the same result.So, if you live in a high signal area you should be fine, if you live in the fringe like I do, you will have to take the phone out of the hard case for best signal.
