Missing key parts to work as imagined. No temperature control and no monitoring of fan.
Ambivalent to say the least. Currently considering a product return as the thing came with no usb dongle interface between the fan controller and sensor, without which it has next to no functionality. No separate power cable for the controller and no port on this particular controller to accept the sensor input. It may work ok. IV sent numerous cries for help over the counterintuitive and useless "instructions" but have not yet heard back. If the dongle I've grudgingly ordered doesn't deliver some function to this mess of wires immediately it'll be getting sent straight back and an AC Infinity system ordered in it's place. Update, pre dongle delivery . AI finally found I don't need the dongle to get the humidistat and temp readings working; merely to use a splitter provided but still without the dongle there is no easy viewing of the fan as a separate unit in the controller/app menu. Moreover the instructions were poor. App doesn't give easy access to better instructionals and those on YT feature controller 43 units with a different port configuration. Information support and instructions need refinement. Product may yet be decent.

I am impressed with the quality of the product. Strongly recommended. You may find cheaper similar products, but the quality won't be at this level.

O kit de ventilador e filtro Mars Hydro é incrível! O ventilador é potente e silencioso, garantindo ótima circulação de ar, enquanto o filtro de carvão funciona perfeitamente, eliminando qualquer odor indesejado. É evidente que o produto foi desenvolvido com materiais de alta qualidade e pensado para durar. A instalação foi simples e o desempenho superou minhas expectativas. Recomendo este kit para quem busca eficiência e confiabilidade em sistemas de ventilação!
