This set of nylon spudgers is excellent.
My Amazon Kindle Voyage is one of my most treasured pieces of electronica. The battery, after 5 years, started to give up the ghost. It is dying in a rapid and dramatic fashion. I really did not want a different model Kindle and the Voyage is discontinued.
I was worried I could not open the Voyage without destroying it. Amazon famously glues things in place and I tend to break plastic bits.
Instead of using a small eye-glass repair sized flathead screw driver, I decided I would try the right tool for the job. This set of spudgers matched with slow and steady movement did the trick. Amazon used double-sided sticky tape to make shit annoying. I was easily able to open the case.
