Review: Hab es jetzt 2 Wochen im Einsatz, bis jetzt alles tiptop, läuft leise, hat power und ist mit der App sehr gut zu steuern. Vor allem jetzt nach dem Update ist es noch intuitiver. Wirklich gut. 👏🏻 hab mal einen 5 mal so teuren Controller von Growbase gehabt, da gefällt mir dieser hier von den Einstellmöglichkeiten etc. eindeutig besser. Von der Haltbarkeit her, werd ich meine Rezension in 1 Jahr noch mal aktualisieren.

*by H***. on 21 May 2025*

I have a couple competitor fans that are of similar style, they either run full speed or have an analog turn dial speed controller, all are 4", I'd say the Spider at 50% puts out almost as much air as the others on full speed. I'm using it to pull air from a server rack, my temporary installation of the fan, it's a bit louder than it should be because of my ducting on one side and the lack of it on the other, plus it's 22" away from my head. Back to the controller, I like how you can can control lights, vent fan, blower fan, not that I'm using the others, but it's nice it can be done from one spot. I'm doing it by temp, I set 40% always on speed and a ramp up to I think 60% above 28C. Once it's in final home I'll tweak the settings a bit more. If I had to list 2 "wishes". 1. i wish I would have gotten the model with the mounting cradle vs the sling. 2. I wish the fan ramp up was more of a ramp up, like a PWM in a computer where ok it's at 40% and 24C, oh it's 25C now, lets ramp up the fan a little to say 45% to see if it'll bring them temps back down rather than wait til 28C and instant full 60% or 100% if that's what you set it to.
