Review on 🦷 BURST Replacement Electric Toothbrush Heads: Charcoal Bristles for Deep Clean, Healthier Smile - 3pk, Rose Gold by Gina Moore

I bought a total of 5 of these devices. All vibrations have different strengths. I am extremely unhappy. Two of them ran out of charge and died completely 6 months after purchase. I hate that Revain won't let you buy a guarantee on it. In addition, only 1 out of 5 purchased has significant sonic pulse power, the rest feel a very gentle vibration. To explain why I bought 5 because of gifts for my family. Extremely dissatisfied. I bought one because it no longer works. I'm afraid that a year after the purchase, even the weaker ones will no longer work. Only the one with significant strength works well.
