I don't have a rhenostat yet but I think you set them for an acceptable temp range and they automatically adjust your heat source appropriately to stay in that range.

As far as the shedding help stuff I think it's probably safe but personally I wouldn't waste my cash on it when good husbandry (proper humidity, misting if needed) would do the same job and costs nothing but your time. Maybe it is required in some circumstances for snakes that just can't shed right now matter what, not sure on that?
