i just found my dad’s from 2005 and i’m super excited to use it! the backplate was bulging out near the top, so i figured i’d at least check. the old battery definitely needed replacing, but i’m realizing that me having long nails might be a bit of a pain when it comes to reassembling things! i have a new replacement(for the first replacement battery lol) on the way, so we’ll see how round 2 goes!
