DODOcase has just announced an updated version of its popular, book-style iPad case with stronger corners and a deeper tray for the tablet to rest in.

In the previous version of the case, the corners were prone to cracking if the solution was dropped. But the new case has a redesigned tray that is said to be 230 percent stronger. The case can also withstand a drop from 2.5 feet without being damaged.

DODOcase said it went through 100 prototypes and conducted more than 250 drop tests to find the best case. Here’s a quick video about the new DODOcase. Click here if you can’t see the video.

The case is also still constructed from bamboo. The refinements only added 9 grams of weight – or as heavy as nine paper clips.

Beyond the increased strength, there is an added hole for the iPad’s back camera, which was an omission on previous cases. The new case also has a bamboo power button to turn the iPad on and off.

The case is compatible with the new iPad and iPad 2 and can be purchased from the company’s website. Prices start at $59.99.
