You splash out hundreds of dollars on a new smartphone or tablet, it’s crazy not to spend a little more in order to make sure it doesn’t get scratched or broken. Our electronic friends serve us faithfully until we drop them in the toilet, leave them at the mercy of inquisitive toddlers, or allow them to slip from our grasp and tumble down the stairs.Skins and design covers can serve for protection and personalization. These are the result of the relatively "naked" designs produced by manufacturers such as smartphone, where the metal and glass components of the device are exposed and vulnerable to damage. They are distinct from holsters, in allowing use of the device while in the case, but in many instances include a belt clip or other device giving it the functionality of a holster. They are made of hard plastic, rubber, or in the newer market adhesive-backed vinyl pieces. Vinyl skins can be ordered on many websites and come pre-cut to fit your cell phone or another electronic device. Vinyl material may be calendared or cast, with the latter being more expensive. Calendered vinyl is expected to only be used for short-mid duration (10 years) while cast vinyl is used on a more long term basis. Calendered vinyl also tends to shrink in the heat and can be shaped into any form (above 80 degrees celsius) but might fade in direct sunlight.The todays standard of calendered films is almost as good as the cast vinyl. You can find a wide range of films at COVER STYL'. Cast vinyl avoids most problems, but costs up to 250% more. 3M has manufactured a cast vinyl product that they call "Controltac". This vinyl cover maintains a more glossy look and provides an air release channel that prevents bubbles during placement. The more popular is the cast vinyl because of the range of designs.Some phones have a replaceable cover. A release button on the cover lets it pop off to be replaced with the new cell cover. Phones that lack a replaceable cover can accept a slip on or snap on cover. These come in leather, vinyl, silicone, or hard plastic.
