Remington Shaver Heads
The R9190 had two hidden screws keeping it together. After prying up the rubber as shown in the photo, the screws were exposed.
The main reason I’m posting this is because I know how much I appreciate it when I find some obscure piece of information on the Internet that allows me to fix something that I’d otherwise have to throw away. I’m disappointed that Norelco and Remington continue to build products whose batteries cannot be easily serviced. I’ve read recently that many cellphones get replaced when their batteries goes bad after around 18 months of use.
