Questions about Remington XR1600 Men's Razor RX7 Ultimate Series

I think - but am not sure - that the shaving heads are designed for 'fine' hair.

This shaver is primarily designed for shaving men's heads with a rotary head system for close, skin-contact shaving. However, it can be used on other body areas such as women's legs. It offers a close shave similar to that for bald heads, which is among the closest achievable without a manual razor. It is suitable for wet and dry use, including with shaving gel or cream, and is 100% waterproof, making it versatile for leg shaving as well. Users have reported it can provide a closer shave on legs compared to some other electric shavers due to its 5 dual track shaving heads designed for maximum skin contact.

The Remington RX7 Ultimate Series bald shaver is waterproof, which means you can use it for both dry shaving and wet shaving. You can therefore use the shaver in the shower without having to worry about its water resistance.

I don't know....have had it since the end of March and use it nearly every day. Charge it once a week!
