THE REFERENCE SHELF
Buying checks
Manual and powered brushes are different purchase systems
Compare the actual complete kit and future refills before comparing sticker prices.
Head-only refills are not a handle kit
Read what the pack supplies before treating it as an electric toothbrush.
Battery and rechargeable describe different ownership details
A powered label alone does not explain the power system.
A head match does not establish a charger match
Refill, handle and charger relationships are separate checks.
