Answer Question
How do I replace the roller heads on the Geopu ZCA019 Electric Foot Callus Remover?
I have been using the Geopu ZCA019 Electric Foot Callus Remover for a while now, and I noticed that the roller head is starting to wear out. I want to replace it with one of the extra roller heads that came with the kit, but I'm not sure how to do it. Can you provide step-by-step instructions on how to replace the roller heads?
