I am thinking about purchasing either the S200D or S200B to work my bulbs in the ceiling which are Tapo smart bulbs.

I am a bit confused about how to attach the S200D's wallplate to the wall if I don't want to use the adhesive stickers. The instructions imply that the original light switch should be removed but I don't want to do this as the wiring would need to be removed from the rocker switch and I may want to use the original switch if something happens to the connection. Can the S200D's wallplate be screwed directly onto the wall by drilling new holes? If so, then does the button just magnetically attach to the wallplate with the ability to remove it at any time or is it stuck to the wallplate like I saw in one particular video?

If I choose the S200B button and do decide to use the adhesive stickers, how is the button removed from the bracket in order to change the battery or reset the button? Does it easily twist off the bracket? I've seen videos where it looks like there are little lugs which need to be twisted.

This may all become obvious if I could see the product but unfortunately I am just going by the instructions so any help and advice would be useful.
