An I missing something? This is literally the same idea as the shabbos lamp, just in a different, not necessarily more useful form. It sounds like price might be a slight advantage, but ease of use seems like a disadvantage.
For traveling it's a lot more convenient than a Shabbos lamp if going to a hotel etc.
Travel is the only convenience this seems to offer.
Is the Kosherswitch being sold?
Ive never seen it. Dont worry, there will always be a need for a Shabbos Goy!
I am out of a job.
Maybe my first HT?
These would be good for a sukkah.
Complete Chillul Shabbos according to most competent rabanim!!!!
