The recesses are in the right places, so that for example the USB / charging cable still fits perfectly. The volume buttons are also surrounded by the case, but can be very smooth and easy to operate - this was in my old case is not the case, there was only very sluggishly. The power button is surrounded by the Case. Here is a recess in the casing, so that the key bit is recessed and therefore you have to accurately press the right spot in this "depression" to press the button. That's pretty good, but you have to get used to it. But unless you have a subject and not as annoying as one might would think. I anyway do not mind.
The case feels pleasant. It has a nice smooth surface. The case is nevertheless good grip. The material feels soft and comfortable.
I ordered the shell in the color "pink". The color is beautiful for my taste. I have the black Galaxy S2 and the fact that the case is slightly transparent, the color looks somewhat like a mix of burgundy and darker pink. I like it very much! The pattern peps up the case, it works just great. Due to the transparency you can still see the Samsung logo on the back good. The case is made more shiny material. Accordingly, one can see fingerprints and grease streaks on the case. It is noticeable already, but it's not extremely annoying in my opinion. I once had a shiny black case, because you could see the fingerprints ten times more than here! The Case acts still great on the phone.
I have not tried it yet, but I'm sure the good case protects from drops. The edges on the front (the display) are slightly higher than the display is - and that's good; because as well as the display is protected if you put the phone to display on a table or the smartphone fall times face down on the ground. In addition, many cases for the SGS II at the upper-right corner have a recess, although there is nothing which would justify the recess. This is due to the following: In Korea there is a version of the SGS II with built-in TV tuner and then on the spot sits the antenna to pull out (?). This version of the phone is not here. Therefore bothers me the free corner - first it looks in my opinion made by stupid and secondly, the cell phone is not protected during a fall at this point! Therefore, I am more than pleased that Prima Case also offers cell phone cases for the Samsung Galaxy S2, which also enclose the upper right corner and there have no recess!
Conclusion:
Because of the beautiful appearance, the fitting accuracy with the 2000 mAh battery, the perfect fit and the matching recesses the case in my opinion 5 star deserved - as though the fingerprints are clearly visible and pressing the power button are used to, gets the Case of me 4 stars.
