My one year old Power Support Air Jacket cracked recently thus bought another case from NUDE by Switcheasy ($31.90) @ local iStore website (Free Shipping for Singapore). At 1st look, the material are quite flexible and decent but the protective film really s*ck. The sticker that let you peel off the film actually make it very difficult to remove (properly due to overdue storage) and make my film quality look bad.
Furthermore, the fitting of the case is not really that tight! (And it quite slippery) Disappointed again! Luckily I bought it for iPod Touch to try 1st as was thinking to buy one for iPhone 4 when I have it! Not recommended!
