I have swapped out all my herpstats and moved all my racks to Johnsons. This makes it easier on me to have a thermostat per rack for better control.

I did have herpstats on my racks but just didnt like the software setup.

I say go johnsons, for 88 shipped you can control 1500 watts worth of heating compared to herpstat or helix having 4-600w rating per outlet.
