Review on AquaSonic 8 Pack Replacement Brush Heads by Danielle Bates

We bought these for our Aquasonic toothbrush set with #RST2030T base. They do not fit. There seem to be several different models; Black, White, Viber, etc. There is NO model number on the electric toothbrush or gas station. The description states which model is compatible with interchangeable nozzles and which is not, but there is no clear indication of how to tell which model the buyer has. As such, ordering replacement heads is a trial and error process. Order one and if it doesn't fit, send it back and get another, and if they don't fit, order another, another? Give us a description so we can order the ones we need to get started! By the way, we LOVE the Aquasonic toothbrush. It works great and is of good quality. Interchangeable heads probably too, if only we could get the right ones.
