Ive heard this all before. No offence but u have no idea who i am or what i been through. I bought a rheostat. Its not like i dont have ANYTHING. and i was told the one im getting works for reptiles. Im on a budget. Just like a million other people are in this country. I only have 35 till my check next week. And all that goes to bills. Id like to get something a little better for my snake. I DO take care of my pets. Furry or not. Ive researched enough and im keeping the proper temps and humidity. My snake isnt stressed. And if it does fail i have a rheostat till i can get something else. I find it a lil retarted to spend $100 on something thats gonna do the same exact thing as a $35.
