does any onwe use heat cable for there spids/scorpions/inverts

i was reading about it and it seems a great way to heat multiple tanks. was just wondering if any have used it before?

They are ideal if you have shelves with hundreds of spiders particularly if breeding species. Having said that these days a lot of t keepers are doing away with additional heating and having the spiders in a spider room which is temperature set higher than the rest of the rooms in the house
