i bought an oral-b in 2023, its a decent toothbrush, but it only has 10minutes of brushing at the most before require charging. most new off brand ones last alot longer, and have even cheaper replacement heads, then the replacement heads(off brand) for oral-b. i use a sonic toothbrush most likely its a off brand, it was 14$ online(electronic display, intensity of oscillations settings, timer), but its been discontinued, likely due to last years tariffs. i see at least 2 other brands with a similar features. all uses rechargable cable, stations. i would only use one with usbc, or plug in. no batteries, too cumbersone to deal with.
