well I just got it so I can not comment on product lifetime but already it goes perfectly with my Kindle. Its weight is reasonable, even 100g or 266g including Kindle! Good only the inscription on the front is so so ... but after all no matter the coverage ;-) For the difference in thickness is acceptable too. And the protection is real because the corners are well protected, and coverage for the very thick screen and with the felt for a soft touch. Here. I will not hesitate to come back if I had a concern for quality.
