Retrofit devices that clip onto what is already there - a finger that presses a switch, a motor that rides an existing curtain track, a lock that fits over an existing thumb turn. For a rented flat or a home where nothing can be altered, it is often the only workable answer.
Recommended for rented flats, for a client who wants to try motorised curtains before committing, and for the odd switch that genuinely cannot be replaced. In an owned home being renovated, a proper motor and a proper switch are better in every way.
