There are times when you want a simple cover for an iPhone or iPad to provide just some basic protection against scratches. The iShine is an inexpensive cloth sleeve in which you can slide an iPad or an iPhone with a drawstring at one end to cinch it closed. The manufacturer sent me a free review sample about a month ago and I've been using it off and on since then. The cloth itself is made of soft microfiber, which means that when it isn't carrying your device, you can use it to clean you screen.
The iPad version of the iShine will hold any model of the iPad, from the original iPad to the new third generation iPad. There is enough space to hold an iPad even when an Apple Smart Cover is connected, but the iShine is even more useful if there is nothing on the iPad screen because then the microfiber cloth will lightly rub against the screen and clean it while it is covered.
The iPhone version of the iShine holds any model iPhone or iPod touch. There seems to be enough space to fit an iPhone even if it is inside of a case as long as the case itself isn't too big. Again, however, you get more out of the iShine if the iPhone is in there by itself being polished and cleaned by the iShine.
I most recently used the iShine over Easter weekend when my family traveled on a plane to visit my wife's relatives. Now that I have a third generation iPad, I let my son use my older iPad 2 on the plane, and I was looking for something simple to cover the iPad 2 and give it some simple protection before I placed it with a bunch of other items in my knapsack. The iShine was perfect for the job.
If you are looking for simple protection for an iPhone or iPad, the iShine is a great option. It is inexpensive, and in addition to covering your device it cleans the screen.
