The SwitchEasy TRIM case for iPhone 4 is one pretty unique case, nothing too surprising coming from SwitchEasy that is known for their very unique case designs. The TRIM does no disappoint in both it's design and quality. Of course some may not fancy the TRIM's look and feel but I can assure you that it is a great protective case for the iPhone 4. You can say that the TRIM is a bit of a hybrid case because it is made out of two different materials, a semi-transparent hard polycarbonate plastic back and a semi-soft frame which feels like a TPU material but I'm not sure.
This semi-soft frame feels a bit like glossy rubber and because of how it's designed (which reminds me of an accordion) it provides you with excellent grip. Your fingers have such good grip because they get in between the grooves on the sides which may be a bit sharp to those who are very sensitive, but nothing to worry about really. These grooves also provide excellent shock and bump protection to your iPhone 4.
