Metric Philips Sonicare 6100 Oral-B iO 3 Manual Toothbrush Purchase price £89 £70 £3 Annual running cost £19 £21 £12 Ownership cost £146 £133 £39 Cost per use £0.07 £0.06 £0.02 Value note Good feature set, but branded heads are the main recurring cost. Lower handle cost with similar ongoing head replacement pressure. Very low cost, but replacement cadence still matters.
