Good so far

Very much like the simplicity and ease of setup
Seems to work well. Still very early in use to evaluate light strength, but seems fine

Great fan and controller is great!

Super handy for controlling the heat and humidity in a grow tent. Haven’t used their fans for any other reason, but I’m sure all their stuff is great
