Herpstats are really great. I couldn't think of anything to complain about. Ive ordered both the basic grounded chord version as well as the ND grounded - and they do an amazing job. The base one, which I have running my incubator...went through a couple test runs and has kept the temp within .2* the entire time! They really are great!

Not to mention I received both of them within two days of my order. That really blew me away! They have my business for life!
