I'm just a casual pleb and didn't want to grind out eggs for 200 different pokemon. It was well worth the money just to have my shiny checklist completed, let alone the rest of the stuff I got in my game from it. I had a huge list of pokemon I wanted, hundreds, some I never thought I'd get, like the Japan exclusive ash hat pikachu, but thanks to this, I got every last pokemon I wanted, and more. The only game I have a physical copy of is Pokemon Sun, and the PowerSaves Pro is amazing with it.
