So, I'm thinking about getting my very first snake, and my friend recommended that I buy a terrarium from Animal Plastics. I saw some people on this and other sites who seemed pretty happy with these terrariums so I figured it'd work out well. But, looking on the site there is a list of add-ons I could get with the terrarium, including locks and Flexwatt belly heat. Is the Flexwatt better than buying a UTH from a different place, and are the locks necessary?
