My boyfriend and I are new to keeping snakes so when we first started out we just used the stick on gauges as well. Upon reading up more on this forum we decided to get two digital Accurites from Walmart ($12) for both the warm and cool side.....from the probe we found out that our warm side was over 100 degrees!! The stick on gauge still said around 85ish! We couldn't believe it...thank god we made the change!![]()
