A good guide but I found removing the bottom quite troublesome. Levering against the charging base felt like it would break the base. I needed to lever it in stages, wedge it and grab and pull it with mole grips. This damaged the plastic a little, but I got it off.

Hmm, maybe they changed the construction. When I created the guide the bottoms (of the 2 toothbrushes I repaired) opened quite easily, but that's good to know.
Also I do not think you need to worry about breaking the base: as most chargers that you plug in the mains, it should be completely filled with a hard resin, and thus be almost indestructible.
