Unfortunately, the product supplied Kindle 3 is not suitable, as its name suggests (the Amazon has now changed). After looking at the manufacturer's website is clear that the framework is suitable only for the Kindle 2 and Kindle DX. The 3rd generation is significantly smaller and slips back and forth. An endurance test I was able to cover so do not undergo, but it makes a very robust impression and was well in hand. It is also possible, the Kindle to solve together with the rubber boot from the cover what the read comfortably in bed or on the couch would be very beneficial.
Should there be a version for the Kindle 3, I'll try this again gladly.
