Review on 🪥 Ronsit Replacement Brush Heads - Compatible with 4/8/12/16/20 Count Electric Toothbrushes - Professional Care/Professional Care SmartSeries/TriZone/Advance Power/Pro Health/Triumph/3D Excel/Vitality Dual Clean (Pack of 4) by Chad Slaughter

Good value, cleans as good as the brand name; My first jet lasted two months before showing any wear and I replaced it (I think the normal three month lifespan for a brand pushes it); the second head lasted about six weeks, and then the gear sort of broke off and stopped rotating during cleaning (never happened with the Oral-B head); my third is only a few weeks old and works perfectly; My son uses one with no complaints. Today I bought an 8-pack from Costco and at the checkout found it was $40; damn much! I am trying other packaging of these generics.
