So I've been reading comments both saying that the iPhone 6 Spigen Neo Hybrid Metal Case does and does not have an effect on signal strength. Therefore, I conducted a test to finally get a solid conclusion. I used the SpeedTest App to test my WIFI speed with and without the case on and got the following results: Without Case 1st Time: (download speed in Mbps, upload speed in Mbps) 4.94, 1.59 3.80, .68 3.73, .37 3.93, 1.62 4.89, 2.67 I then put on the case: 2.15, .55 2.72, .50 4.35, .34 2.24, 1.28 1.68, .28 And finally took off the case again: 5.21, 3.44 4.51, 1.77 3.68, .65 3.74,1.28 3.65, 0.54 Clearly by these numbers we can conclude that the case has an effect at least on WIFI signal by about 1-2 Mbps. Just thought you guys might be interested to see the results. UPDATE 1: Ran another test for WIFI and Cell Data. Bottom 3 on each list are with the case and top 3 are without. Take of it what you will lol. The Versus Metal case should be here soon so I am hoping that the Versus is somehow better, at least for WIFI. UPDATE 2: I did the field test (mentioned below) with and without the metal band and it seemed to stay just about the same if not exactly the same. This test seems very accurate so I'm going to conclude that the metal case does not have an effect on cell service. If it does it is very minimal and probably not noticeable. This probably explains why the SpeedTest results above didn't really give any conclusion on whether the metal band affected data speed.
