I've been an OtterBox user for years, this Symmetry Series Case for iPhone 6 is the slimmest one I've used. It's sturdy & thinner than the Commuter Series. I like the design and color combination (Blue Print II).
I think this case is amazing. I had an OtterBox on my iPhone 4 which protected it for the three years that I had it. I am sure that this new case will serve me just as well. My only slight complaint is that the buttons (Power on/off and volume) are a bit harder to activate now that they are ensconced in the case. This actually may be a good thing as it will prevent the phone from going on and off in my pocket and thus save battery power!!
I like how thin the cover is so that it does not grow the size of my iPhone 6, while adding all the protection needed from droping the phone (even on the driveway). I also like how I can grip the phone with this cover (the iPhone 6 without it is just too slippery). The cover was easy to put on and also easy to take off (only needed to do so to get a screen protector put on). I highly recommend this cover. I like the two toned look of the cover. Well thought oout: The dark grey coler looks great next to the screen and does not distract from the function of the phone, while the other color (I choose blue) on the back and sides is great.
i have used the commuter, defender and now this case/synergy. the defender is great protection with the screen cover and added rim about the case, however, it makes the slim phone more bulky. i prefer the commuter case. i purchased a screen cover for this case and for light use, in the purse or what not, i believe the iPhone 6 has good protection. this case appears in the photo to be 2 pieces, but it is only one. the other two cases have the hard shell liner and the rubberized out case which affords more protection.
The sides of the case are soft rubber and can start peeling if you handle the phone a lot. I was hoping that this case would be a good replacement for the iPhone 4 reflex case which had a rubber inside and full hard plastic outside which made it durable enough to last four years until I replaced my phone.
