Sanho is one of those accessory vendors that makes the Apple ecosystem better. They don't try to rip off Apple or other accessory vendors with cheap knockoffs. They either build a better mousetrap by improving on an existing accessory or they invent something new that you didn't know you needed until you saw it! You might know of them under their brand name HyperMac and their HyperJuice external batteries for MacBooks, iOS and USB devices.
An example of a better mousetrap is their iPad stylus. Now every vendor seems to have a stylus, and sure their stylus can also be used as a ball-point pent. But what sets it apart is they have a built-in magnet, so you can swipe in the right spot and awaken your iPad from its slumber! This is a nice touch and shows that they are iPad users as well as accessory vendors.
Apple finally made an iPad case (really a cover) with a lot of design built-in. But it doesn't cover the back. A number of accessory vendors have stepped up to the plate with covers for the iPad 2's back, but the HyperShield goes one better. Sure they offer all of the colors Apple does, but they also have a limited edition Denim cover!
Now when you buy your back-to-school clothes you can get an iPad 2 case that matches! When you consider how many schools are making iPads part of the curriculum, being able to quickly identify yours will be important. The denim HyperShield is a limited edition so if you act now, you will probably be the only one in the school (or town) with one! Or, mix-and-match to match your school's colors!
