Marketing the product as Lechatchilu on shabbos is probably an overreach. Akuperma’s take is very apropos although it does have the randomness built into it which makes it a bit better – makes it less a gromo. I would imagine its use would be best fit in hospitals or in homes for the elderly and maybe yuntiff for a tzoyrich.
With respect to the miskavein issue i believe there are those who hold that melechis machshevet works both ways so that just like when you do not intend a melocho its muttar midoraysa no matter your action when you intend a melocho its assur as a gromo no matter the action you take – but that is clearly not the general opinion and represents a small minority view.
