Friend let me know. I've been thinking of getting a Herpstat 4 as I've got a Herpstat 6 right now but come middle of July, I'll have 9 cages and only got one Herpstat 6 and one Herpstat 1 Redline. Of course, I won't have the cash on hand as I need to make my final payment on three loaded AP T25s haha. But figured I'd let anyone on here know in case they were getting ready to get one.
