I only post my next question on here and hope for a response here so I can stop spamming the forums with posts

I'm preparing to order everything needed for my terrarium before I get my snake. The only hiccup I've found for ordering is temp guns, all of the decently low priced ones are saying "will be within 10 degrees" which isn't a big deal for them but with us I feel that is quite a big deal?

With that being said, what temp guns do all of you use?
