I really like these replacement toothbrush heads for my BURST electric toothbrush. They seem to last a very long time compared to many other toothbrush heads I have tried. The bristles hold up really well and do not get worn down or frayed quickly, even with regular use. While I still try to replace my toothbrush heads routinely for hygiene purposes, I honestly feel like these could easily last for several months if needed. The replacement heads attach perfectly to the toothbrush and feel very secure once connected. I also appreciated that they offer them in pink because it matches my toothbrush perfectly and adds a fun touch. The price also feels pretty reasonable for a three-pack considering the quality and durability of the heads themselves. My only small complaint is that they are made of plastic, which I personally do not love from an environmental standpoint. I also am still undecided about the black bristles because it can make it harder to tell if the toothbrush is fully clean after use. Other than that, the product arrived exactly as described and pictured, and overall I think these are excellent replacement heads for anyone using a BURST toothbrush.
