This article mainly from the material and workmanship aspects of the selection of flat shells we give some suggestions,we can choose according to the needs.
Texture of material
First, we should understand that the quality of protective covers and inferior materials are different. The high quality front cover is made of polyurethane, which can be felt by hand. It has a good handle, and its elasticity is good, so it will not easily deform. We can fold it in half by hand to see how elastic it is, if it is not deformed, it will be of high quality; and the PU material used in the rear case will be more resistant to wrestling, compression and even the rolling mill will not be damaged. The materials used in Shanzhai usually contain toxic chemicals, which are almost inelastic, easily deformed, have a relatively large odor, and are extremely harmful to human body, and even lead to disease.
Two, there is a clear difference between workmanship and poor quality iPad protector in terms of workmanship. Excellent workmanship, no wool edges, and the feel is smooth, will not hurt our love machine. Its heat absorption and sweating can keep the display clean. The rough workmanship of Shanzhai products will have flaws in the corners, which may scratch our fingers.
Three, lining is not just different appearance, but also the material used in lining can distinguish their authenticity. The material used in the front cover of the high quality protective cover is super fine fiber, which is smooth and meticulous. The biggest point is that it is not easy to scrape the screen and have the effect of cleaning the screen. Those inferior interior has very big impurity, some still have a little black dot.
