I used a Philips for about 7-8 years. Liked it well enough that when the battery died, I bought another.
Regardless of which brand you buy, pay attention to the replacement heads, they can be expensive. Not too far off from how printer ink costs more than the printer.










The only new car I’m aware of that should not monitor you would be the Slate pickup. Early in their development they mentioned this as a feature, but they haven’t brought it up in a while. So something to double check.
