A bit difficult to pry open the case - plastic pry tool didn't work for me.

My Problem

Battery life between charges was too short.

My Fix

I could not pry open the case with the plastic tool provided. I needed to use a strong knife blade, probably a no-no, but it worked! Be very careful not to damage anything!

My Advice

The screws are real small, almost microscopic! Make sure you have a good solid container, such as the box the kit comes in to keep track of the screws or buy one of those magnetic mats. My old eyes don't work as good as they used to , so make sure you have a well lit work area and make sure you know which screw goes where when you put it back together. When putting mine back together, most of the screws did not get very tight, but I wiggled and shook them to make sure they were in place. Patience is a virtue with this battery replacement.
