There are not many accessories brands that have passed Apple's official certification and put on the shelves of the Apple Store, tech21 from the United Kingdom is one of them, which has made great achievements in the field of electronic equipment protection, and the protective materials used have passed the drop impact test of the National Physical Laboratory (NPL) in the United Kingdom, which is the top level in the industry.
 
Tech21's product line is relatively clear and simple, priced at 198-398 yuan, only the rhombic series is a silicone soft shell, and there are slightly stiffer canvas leather shells and transparent hard shells to choose from. The former is more versatile, overall durable, and can choose different colors according to personal preferences, while the design of canvas and leather is more business-oriented, and the style is stable and imposing.
 
Among similar products in the 200 yuan price range, the Tech21 Liberty light luxury series has the most outstanding design, which excavates the tough style of most brands, and the product color scheme is diverse. The Liberty light luxury series is a collaboration with the London Liberty Department Store, its pattern comes from the French totem Marham, using a variety of geometric elements and exaggerated color combinations, full of European court style, although fancy but not cheap, compared with the black and gray tough guy phone case, the Liberty light luxury series is more neutral. At present, this series is only compatible with new 2018 models such as iPhone XS/MAX/XR.
 
Tech21's quilted series is the first choice for people who are simple, and its compatible models cover iPhone 7/8 and above. The protective performance of the phone case mainly comes from solid materials, the feel is slightly thick, the grip of users with small hands is not very good, and its back is smooth, relying only on the texture of the side bezel to enhance friction, the use experience is slightly reduced. Canvas and leather phone cases do not have such problems, but the price is 100-200 yuan higher.
 
tech21 mobile phone case is made of self-developed FlexShock material, although it can provide strong protection for the mobile phone, but it must be achieved by thickening the mobile phone case, which is still silicone in essence, and its vigorously advertised vertical bar shockproof structure can only provide a weak shock absorption effect, the so-called "molecular structure from soft to hard", "absorb violent vibration" and other statements are all publicity gimmicks, consumers do not need to pay too much attention.
 
At present, Tech21 has many sales channels in the Chinese market, and consumers can buy it through Apple's official website or e-commerce platform. Although the product is very resistant to falling, and the official has even held an event in China to shoot basketballs using Tech21 mobile phone cases, it is not recommended that consumers blindly imitate it, and there is still a risk of broken screens.
