It’s our mission to provide you with the smartest tech protection on the planet – while taking some of the stress out of everyday life. In order to do this, we put our phone cases products through tough testing methods that ensure we crush the competition when it comes to keeping your device safe from damage.

Tech21 vs competitors


Our experienced in-house science and materials team push the boundaries to develop innovative impact materials and then test them using methods independently approved by the UK’s National Physical Laboratory – the market leader in cutting-edge measurement science.


The NPL has developed and maintained measurement standards for over a century and only endorses products and services that fully live up to their claims. This means when we show you the results of our drop tests over 20 separate incidents, you can have complete confidence in them – and Tech21’s products.

With a focus on how you would use your device in the real world – we don’t do unrealistic publicity stunts like other protective tech companies – we can back up all our claims with rock-solid science. Below you’ll find links to see how our most popular cases completely outperform the competition when it comes to keeping your device safe from damage.
