In a recent review, customers shared their experiences with the Pursonic 8 pack replacement brush heads, specifically discussing their compatibility with various models and the overall reliability of the product. The FAQ section indicated that the brush heads fit the Diamond Pro Series and Bling Dental Products Diamond Toothbrush, though there were uncertainties about compatibility with other toothbrush models such as the Aquasonic and S452. One user reported that the replacement heads did not fit their electric toothbrush and had to be returned. Additionally, there were concerns about the country of manufacture and the perceived lower quality associated with Chinese-made products. While some users found the replacement heads easy to use and equivalent to the original ones, others expressed dissatisfaction with the quality, durability, and fit of the product. One customer mentioned receiving only a 3-pack instead of the expected 8, while another observed that some of the heads did not fit their toothbrush. Some users reported that the bristles did not retain their shape after a couple of weeks of use, and expressed disappointment over the insufficient cleaning performance.
