I modded this $4 Goodwill shaver to use rechargeable AA batteries instead of futzing around with plug-in chargers! It has twice the power it had before, works great, and looks substantially less like a bomb than my last Frankenshaver.
Other than shocking myself with wall current, inhaling toxic fumes, and accidentally cutting into the rechargeable batteries with my power tools, things went well.
Goodbye old shaver! Thank you, you have served me well!
