Have been using the silicone case for about a month now.
-good protection in case you drop the phone,
-the phone is not slippery any more so the chances of droping it are minimized
-better protection in case someone spills a glass of water on the table you have your phone on (personal experience )
-it is virtually impossible to scratch your phone
-the extra size added to the phone is minimall
-at first the phone is a bit uglier (after a while u get used to it)
-can`t put it in a pocket with the same ease due to the fact that it is not as slippery as before.
-each time you want to remove the back cover (micro sd or sim swapping)
you have to take off the case.
personally i recommend it..
