Besalel, there is a very serious downside.
The downside is the possibility of Chillul Shabbos ch”v.
Please speak to your Rav before deciding that this belongs in your home.
In the case of a choleh, or sick person, the Halacha may be more lenient. But the downside is such that I don’t think we should act without consulting an expert, just as you wouldn’t decide on your own what medication to give a choleh (unless you’re a doctor).
