So i don't mean to sound rude..... But you said "i only have 35$"
You purchased a snake, put its life in your hands, and only have 35$ For the HANDS DOWN most important item when owning reptiles?
What if it fails (like they have been known) now your vet costs min 100$ to help you (IF YOU EVEN HAVE the $$) All of which could be saved by spending the extra few bucks on a Thermostat MEANT for reptiles not plants... Sorry biggest pet peeve is people trying to cheap there way out of a Real thermostat (unless that is a temp fix to nothing while proper is being shipped)
