Questions about Remington XR1600 Men's Razor RX7 Ultimate Series

Is the shaver waterproof? Can I shave my bald head in the shower?

I dropped the razor head and all 5 blades came out of the holder. I have tried to put everything back in, but it won't hold. I have not found any instructions on the Internet. Can anyone help me?

I am undecided whether to buy it, I have a few moles on my head and I am afraid of ruining myself every time I use it, is it that aggressive?

Are there replacement blades/heads available? Where do you get them?

Hello everyone I wanted to ask if there is an attachment to shave a 2mm haircut? I have seen that attachments should be included, but not which ones, or which length can be cut with them Thanks in advance

How long does the shear head last? (With normal use, every 2-3 days). Depending on that, one could look past the price and the impossible procurement of shear heads.
